| Anomálne škálovanie v turbulentných systémoch s narušenou symetriou | |
| Anomalous scaling in turbulent systems with symmetry breaking | |
| Program: | VEGA |
| Project leader: | RNDr. Jurčišin Marián, PhD. |
| Annotation: | Turbulent behavior belongs among basic properties of various macroscopic physical, chemical, biological,social-economical, financial, as well as environmental systems. Typical well-known examples of turbulent motionsare various atmospheric phenomena (tornadoes, hurricanes, cyclones, etc.), turbulent streams in rivers andoceans, and turbulent motions in electrically conductive environments (motion of the outer earth core, solar wind,etc.) . The main task of theoretical investigations of turbulent systems is, first of all, the understanding offundamental physical properties of turbulent flows that are common for all turbulent systems and which couldpotentially be applied in technical praxis in the future. In this respect, the main aim of the project is theinvestigation of the influence of breaking of various symmetries of developed turbulent environments on theproperties of the anomalous scaling of correlation functions of fluctuating fields as well as on universalcharacteristics of turbulent systems. |

| Klasicko-kvantový prechod v mechanických rezonátoroch | |
| Classical to quantum crossover in mechanical resonators | |
| Program: | VEGA |
| Project leader: | RNDr. Človečko Marcel, PhD. |
| Annotation: | The material variability and dimensional diversity of mechanical resonators allows us to deliberately change their physical and geometric properties. Thus by reducing their mass / energy content (i.e. by decreasing their size)while simultaneously cooling them to temperatures close to absolute zero, it is possible to use them as a tool tostudy the crossover between classical and quantum dynamics. The ambition of our project is (i) the study of nonlinear processes in macroscopic resonators based on piezomaterials, (ii) the study of the transition between classical and quantum dynamics by using our custom made mechanical micro and nanoresonators and (iii) to deepen the understanding of fundamental processes of the energy exchange between these resonators and thethermal reservoir leading to the decoherence. |

| Project leader: | prof. RNDr. Samuely Peter, DrSc., akademik US Slovenska |
| Annotation: | Within the project we will focus on development of particular devices based on superconductors orsuperconducting circuits working up to quantum limit. One of the main goal of the project is a practical amplifierwhich bring real and considerable improvement over the high electron mobility transistor (HEMT) amplifiers. Ouraim is to go beyond the state-of-the-art and fabricate subquantum-limited parametric amplifier, a key element forquantum information processing with microwaves. In order to achieve this aim we will investigate novel quantummaterials which can improve properties of quantum devices. Therefore, the fundamental research of newtopological materials including topological insulators and superconductors will thus be a logical and integral partof our project. |

| PSI – Prechod supravodič – izolant | |
| Superconductor – insulator transition | |
| Program: | SRDA |
| Project leader: | Mgr. Szabó Pavol, CSc. |
| Annotation: | The project aims at understanding the problem of how superconductor transforms to insulator at increaseddisorder. The questions of what is the force driving the superconducting transition temperature to lower values inultrathin superconducting films and what is the mechanism of the quantum phase transition betweensuperconducting and insulating states will be addressed experimentally as well as theoretically. Thesuperconducting films of various content with thicknesses down to few atomic layers as well as thenanostructures and resonators on their basis will be prepared. Transport, microwave and optical properties ofthese objects will be investigated. By means of the subkelvin scanning tunnelling microscope the spectral mapsof the quasiparticle density of states at ultralow temperatures and in high magnetic fields will be measured. Wewill explore possibilities to prepare sensitive photon detectors and amplifiers based on ultrathin disorderedsuperconducting films for the spectroscopy in physics, chemistry and biology.Dynamics of the surface states in another macroscopic quantum object, the superfluid 3He which is thetopological insulator at ultra low temperatures, will be investigated experimentally as well as theoretically. Theobjective is to elucidate the dynamics of surface bound excitations in superfluid 3He by means of mechanicalresonators and resolve if the excitations can be identified with the long searched Majorana fermions.By experiment the recent question if samarium hexaboride is a topological insulator will be addressed. |
