Research performed here brought various interesting discoveries and helped to deepen understanding of trivial as well as nontrivial features of diverse superconducting systems. Just to mention a few \u2013 we brought the first experimental evidence of the two-gap superconductivity in MgB<sub>2<\/sub> and confirmed existence of the two gaps also in pnictides and NbS<sub>2<\/sub>. On the other hand we showed that in some systems the experimental results of other groups were misinterpreted claiming multi-gap superconductivity in materials that are intrinsically single-gap superconductors (Mo<sub>8<\/sub>Ga<sub>41<\/sub>; CuTi<sub>x<\/sub>Se<sub>2<\/sub>; Bi<sub>2<\/sub>Pd,\u2026). We found bulk Ising superconductivity in transition metal dichalcogenides, we studied in details interplay of superconductivity with other order parameters (charge density waves, pair density waves, ferromagnetism) or at the edge of superconductor-insulator transition.

In case of magnetic systems, low temperature interactions like the Kondo effect can screen magnetic moments of certain materials (e.g., those containing some lanthanoids and actinoids), resulting in a loss of degrees of freedom. The system can compensate this loss by forming a narrow density of states structure right at the Fermi energy. This many body resonance gives rise to a variety of exciting low temperature properties such as Fermi- and non-Fermi liquid, heavy fermion behaviour, intermediate valence or heavy fermion superconductivity. By means of measurements at very low temperatures (mK), at high magnetic fields (H &gt; 10 T) and hydrostatic pressure, it is possible to derive the most important interaction mechanisms and establish the relevant phase diagrams. The team from CLTP has long standing experience of study strongly correlated electron systems e.g. SmB<sub>6<\/sub><a href=\"https:\/\/www.nature.com\/articles\/s41467-018-02908-7\">\u00a0[P.
