| Preliminary scope of work in English |
| UTe2 is a fascinating material restoring the interest in unconventional superconductors. It attracted extreme attention after the report of SC, which appeared in early 2019. Since then, every new paper dedicated to UTe2 reveals the exceptional properties of this system. The relevant publications contain an excellent set of delicate experimental and theoretical work. An extreme consequence of the hitherto knowledge is the proposed chiral superconductivity of UTe2 hosting Majorana zero modes. This property puts UTe2 on the list of possible candidates for materials suitable for topological quantum computing.
The measurement of the angular dependence of heat capacity in the superconducting state allows to probe the momentum-dependent SC gap function in anisotropic superconductors. This will add additional constraint on the character of SC phases and significantly extend current knowledge. The experiments will be done in MGML (www.mgml.eu) and are part of ongoing GACR project 22-22322S Unconventional superconductors under extreme conditions. |
