TopoSQ2D – Topological superconductivity in quantum two-dimensional devices
Topologická supravodivosť v kvantových dvojrozmerných zaradieniach
Program:	IMPULZ
Project leader:	RNDr. Gmitra Martin, PhD.
Annotation:	The project aims to explore quantum physics in van der Waals 2D materials focusing on discovery of emergent quantum phenomena induced by the spin-orbit coupling and its interplay with magnetism, topology and superconductivity. For this purpose we establish a new Quantum Materials research laboratory with tightly merged theoretical expertise in spin-orbit coupling and experimental expertise in superconductivity. Research will be focused on investigating electronic properties of the prepared heterostructures in normal and superconducting phases using scanning tunneling microscopy and magnetotransport measurements. The theory will be intended for calculation of electronic structure from first-principles and quasiparticle interference spectra and transport properties in order to interpret experimental results and guide further experiments. The studied systems will be further recast towards proof-of-principle devices utilizing topological aspects of superconductivity relevant for quantum computations.

STRIPEX – Influence of dynamic charge stripes on quantum magnets and superconductors in extreme conditions
Vplyv dynamických nábojových pásov na kvantové magnety a supravodiče v extrémnych podmienkach
Program:	SRDA
Project leader:	doc. RNDr. Gabáni Slavomír, PhD.
Annotation:	The project is aimed at solving the urgent fundamental problem of the genesis of the so-called of dynamic charge stripes (DCS) – inhomogeneous distribution of conduction electron oscillations – and their influence on the properties of strongly correlated electron systems (SCES). The charge stripes play an important role in the high-temperature superconductivity (HTSC) of cuprates and also underlie the mechanisms responsible for the colossal magnetoresistance in manganites, cobaltites, iron-based HTSCs, etc. Observing directly the effect of DCS on the scattering of charge carriers in the mentioned SCES is very sophisticated due to their complex composition, low symmetry of the crystal structure and high sensitivity to external conditions. Instead, it is suitable to use model SCES. Such model materials are rare earth dodecaborides (RB12) with Jahn-Teller structural instability and electronic phase separation on the nanoscale range, in which the appearance of dynamic charge stripes was reliably determined for the first time both for superconductors (ZrB12, LuB12) and for quantum magnets (R = Ho, Er, Tm). The comprehensive study of DCS will be extended by additional model systems based on hexaborides (RB6) and frustrated quantum magnets based on rare earth tetraborides (RB4), and will includes the influence of external extreme conditions such as very low temperatures, high magnetic fields and pressures.

Magnetická frustrácia a kvantové oscilácie v kvázi 2D a 3D boridoch
Program:	VEGA
Project leader:	doc. RNDr. Gabáni Slavomír, PhD.
Annotation:	Borides form a broad class of materials with diverse physical properties. Metallic geometrically frustratedmagnetic tetraborides (REB4), where RE represents an element from the rare earth group, are quasi-2Dfrustrated systems with different anisotropy strength and the same crystal lattice. These systems form an idealenvironment for studying the connections between anisotropy and magnetization processes. With the help of thedeviation of the magnetic field from the easy axis of magnetization, it will be possible to observe thosecomponents of inter-spin interactions that do not appear when the field is oriented in the direction of the easyaxis, which will contribute to the development of more accurate theoretical models. By studying quantumoscillations in SmB6, which is considered to be a representative of strongly correlated topological systems, and in other selected hexaborides, it will be possible to contribute original results to the long-standing debate whetherSmB6 is a topological insulator or not.

LSD – Low-dimensional Superconducting Devices
Nízkorozmerné supravodivé aparáty
Program:	SRDA
Project leader:	Mgr. Szabó Pavol, CSc.
Annotation:	Ultralow temperatures have become an important tool for new research avenues in nanoscience, materials research and particularly in quantum nanotechnologies. Scaling down a physical system towards the sizes when the quantum properties surpass classical physics opens a plethora of new quantum-driven effects, thus giving rise to new classes of quantum materials. Within the proposed project we will focus our study on low-dimensional quantum devices, heterostrucures consisting of atomically thin superconducting slabs and aditional layers with different order (inslulator, metal, ferromagnet). In such systems symmetries can be broken possibly allowing for non trivial topological quantum states relevant for future technologies. Atomically thin layered materials are systems with zero limit bulk-to-surface ratio. Their physical properties are strongly affected by interfacing with other systems. Therefore, they represent an accessible platform for the abundance of quantum effects that can be engineered by combining them into vertical stacks using exfoliation techniques. One identifies two types of layered systems – atomically thin artificially prepared van der Waals heterostructures [Science 353, aac9439 (2016)], and naturally layered three-dimensional crystal systems. A special class of naturally layered materials is misfit structures combining alternating atomic layers of hexagonal transition metal dichalcogenides and slabs of ionic rare-earth monochalcogenides in the same superlattice [APL Mater 10, 100901 (2022)]. They feature new state of quantum matter, the Ising superconductivity resulting from broken inversion symmetry and strong spin-orbit coupling as has been recently shown by us. The misfits are also exfoliative and thus incorporable as units in vertical stacks.

Project leader:	RNDr. Pristáš Gabriel, PhD.
Annotation:	Superconducting materials have become an integral part of the latest technologies such as quantum computers,single-photon detectors, magnetic resonance, SQUID, etc. Achieving room-temperature superconductivity is nomore the only goal, but targeted improvement of superconducting parameters (upper critical field, criticaltemperature) for application needs is the key. Extreme conditions in the form of very low temperatures, highpressures and reduction dimensions into quasi-two dimensions are very powerful tools in this endeavor. Inparticular, in case of thin films the superconducting properties can be tuned by several external parameters (e.g.film thickness, substrate, interfaces). The main goal of the project is to improve superconducting parameters ofthe high-entropy alloys and other materials in the form of thin films in purpose for use in future quantumapplications technology.

NANOFLIT – Nano-functionalization of liquids for liquid-immersed transformers
Nano-funkcionalizácia kvapalín pre olejové transformátory
Program:	SRDA
Project leader:	RNDr. Rajňák Michal, PhD.
Annotation:	The current increase in electricity consumption and the greening of its distribution, together with the increase in the price of materials for the production of distribution transformers, represent a challenge for applied research in electric power engineering. The intention of the presented project is to respond to this challenge by functionalizing the current liquids used in electrical transformers in order to increase their cooling efficiency while maintaining or improving their dielectric and insulating properties. For this project, the liquids used in the distribution transformers of the manufacturer interested in this research will be selected. These are commercial liquids primarily based on liquefied natural gas, synthetic and natural esters. Based on current state of the art, the liquids will be functionalized by means of nanotechnologies and nanomaterials, which can significantly improve thermal conductivity, natural and thermomagnetic convection, and thus make the overall heat transport in the liquids more efficient. The functionalizing nanoadditives will be mainly made from carbon (fullerene, nanodiamond) and iron oxides or other ferromagnetic elements. The functionalized liquids will undergo laboratory measurements of physico-chemical, electrical, magnetic and thermal properties. Based on the analyzes of laboratory experiments and numerical simulations, nanofluids with the greatest potential for improving the thermal and insulating properties of the transformer will be selected. The selected nanofluids will be tested by the industrial partner (the customer of the research results) and applied in the selected distribution transformer. The transformer will be subjected to electrical and temperature rise tests. One can expect that the nanofunctionalization of the liquids will result in a lower operating temperature of the transformer, which can lead to an extension of the transformer service life and to the production of smaller transformers.

Finally, the conjugate will be imaged using optimized MRI techniques tostudy the drug distribution in the lungs in ARDS. The output items of the project have a direct application potentialfor clinical practice.

MagNaFs – Magnetic nanoflowers for biomedical applications
Magnetické nanokvety pre biomedicínske aplikácie

Project leader:	RNDr. Khmara Iryna, PhD.
Annotation:	Today, nanoscale materials are of great interest for their potential to be used in a wide range of areas, especially in biomedical applications such as detection, early diagnosis and effective treatment of oncological disease. One of the therapies that are actively being developed is magnetic hyperthermia (MH) as an alternative approach for the local treatment of tumours. MH utilizes the heat generated by the magnetic nanoparticles (MNPs) when are subjected to an alternating magnetic field. Thus, the better MNPs are heated, the lower concentration of MNPs in the cancer tissue is required resulting in reducing the risk of side effects. Therefore, the heating ability and heating rate of these MNPs is extremely important. In this regard, the clustering of MNPs into nanoflowers, novel systems in terms of morphology showing a structure similar to a flower, can improve their heating rate of these MNPs is extremely important. In this regard, the clustering of MNPs into nanoflowers, novel systems in terms of morphology showing a structure similar to a flower, can improve their heating characteristics compared to their building blocks, i.e. monocrystals of MNPs and thus increase the heating efficiency of MH.

Pružné mikroštruktúry a mikroroboty pre biomedicínske labon-chip aplikácie

Project leader:	doc. Ing. Tomori Zoltán, CSc.
Annotation:	The development boom of biomedical lab-on-chip (LOC) applications during the last two decades brought the need for the miniaturization of conventional mechanical actuators, sensors, and manipulators. Light-driven mechanical microstructures, trapped and moved by optical tweezers, can be easily integrated into the microfluidic LOC environment. The vast majority of light-driven microstructures is prepared by two-photon polymerization. It is the main objective of the present project to exploit the possibilities of working with flexible (deformable) microstructures, which were not used in biomedical applications, yet. Two well-defined LOC application areas are targeted: micro-rheology and single-cell manipulation. Micro-viscometers utilizing the effect of the surrounding fluid medium on the deformation (deflection) of flexible micro-cantilevers will be developed. The novel viscometer devices will be either anchored to the bottom glass surface or kept mobile and optically transportable inside the micro-fluidic system. Light-driven elastic micro-robots will be designed and tested for capture, transport, and release of single live cells. The operation of the developed micro-manipulators will be automated to build multicellular systems, mimicking the tissue conditions, in an autonomous way. To facilitate the flexible microstructure development and optimization, the material properties of the photo-polymers will be determined by comparing experimental deformation data with the results of numerical simulations.

Elektrokatalyzátory pre efektívnu produkciu vodíka pre budúce elektrolyzéry a palivové články

Project leader:	RNDr. Baťková Marianna, PhD.
Annotation:	The development of activities in the field of hydrogen technologies was also supported by the EuropeanCommission in the strategic document "Hydrogen Strategy for a Climate Neutral Europe". Today, Slovakia hassuggested own national hydrogen strategy. Already in 2015, the National Hydrogen Association has founded tosupport research, implementation and use of hydrogen technologies. The Hydrogen Technology Center is beingestablished in Košice with the main "Power-to-Gas" concept using renewable power energy sources with nonegative impact on human life and without dependence on fossil fuels. A significant source of hydrogen is waterand the electrolysis of water is the most promising technology for hydrogen production. However, before it can berecognized as an economically significant resource for large scale application with an exceptional energy potential,the simple, efficient, and secure methods of hydrogen retrieval have to be developed. For the time being, the mostefficient electrocatalysts in terms of overpotential for hydrogen evolution reaction (HER) are noble metals.Unfortunately the high cost and scarcity of noble metals motivate the scientists to find the rival low-cost alternatives. Intrinsic structures of TMP meet the criteria of outstanding electrocatalysts that could further improvetheir HER performance in membrane electrode assembly. Excellent dispersity of electrocatalysts allows full use ofactive sites on catalysts to participate in electrode reaction to improve the electrocatalytic efficiency. Therefore, themain challenge in this project is to reduce the production cost of HER and at the same time to maintain the highefficiency of polymer electrode water electrolysis. Substantial aim of the project will be devoted to improve the PEMwater electrolysis components mainly electrode materials based on modified carbon fibers electrocatalysts result inthe technology which should be more approached to commercial markets.

Project leader:	RNDr. Vargová Hana, PhD.
Annotation:	The project is aimed at a comprehensive understanding of possibilities and limiting factors of electron spin systems for a quantum computation and quantum information processing, which will be investigated by the combination of advanced analytical and numerical methods including among others exact mapping transformations, localized-magnon theory, exact diagonalization, tensor-network methods, density functional theory, Monte Carlo simulations and density-matrix renormalization group method. In particular, we will examine the possibility to stabilize a bipartite and multipartite entanglement as a genuine quantum phenomenon needed for a quantum computation and quantum information processing at least up to temperature of liquid nitrogen or preferably room temperature. We will also explore the capability of the pulsed electron spin resonance for the spin-qubit manipulation. Quantum spin systems with topologically protected edge states eligible for a topological quantum computation will be investigated in detail together with a few selected quantum spin chains studied in connection with the implementation of a quantum teleportation. Frustrated Heisenberg spin systems supporting either the presence of a nontrivial skyrmion phase or magnon-crystal phases will be investigated in connection with the possibility to store a quantum information or to implement more complex quantum circuits. Heterostructures composed of atomically thin layers coupled by van der Waals forces will be examined with respect to a superconducting pairing and topological quantum computation. The studied electron spin systems will be either motivated by the effort to understand unconventional behavior of existing real magnetic materials or will be supplemented by the respective proposals for their experimental realization.
