Type-II superconductivity in the Dirac semimetal PdTe2
Ritu Gupta, Catherine Witteveen, Debarchan Das +2
We report on the microscopic superconducting properties of the Dirac semimetal PdTe2. In this study, we have focused on mosaic crystals of PdTe2, and used detailed zero field and t…
Influence of pressure on properties of multi-gap type-I superconductor BeAu
Rustem Khasanov, Riccardo Vocaturo, Oleg Janson +7
We report on studies of the superconducting and normal state properties of the noncentrosymmetric superconductor BeAu under hydrostatic pressure conditions. The room-temperature eq…

Unsplit superconducting and time reversal symmetry breaking transitions in SrRuO under hydrostatic pressure and disorder
Vadim Grinenko, Debarchan Das, Ritu Gupta +7
There is considerable evidence that the superconducting state of SrRuO breaks time reversal symmetry. In the experiments showing time reversal symmetry breaking its onset t…
The single- vs. two-gap scenario: the specific heat and the thermodynamic critical field of BeAu superconductor
Rustem Khasanov, Ritu Gupta, Debarchan Das +2
The puzzling situation where some thermodynamic quantities require a single-gap description, while others need a more complex gap scenario, is discussed. Our approach reveals that…
