Origin of the Unusual Temperature Dependence of the Upper Critical Field of Kagome Superconductor CsV3Sb5: Multiple Bands or van Hove Singularities?
Ramakanta Chapai, Alexei E. Koshelev, Matthew P. Smylie +8
Van Hove singularities (vHs) located close to the Fermi level in Kagome superconductors AV3Sb5 (A = K, Rb, Cs) have profound influence on their electronic and transport characteris…

Fermi Surface Topology and Magneto-transport Properties of Superconducting PdBiSe
Ramakanta Chapai, Gordon Peterson, M. P. Smylie +5
PdBiSe is a rare realization of a superconducting metal with a non-zero topological invariant. We report the growth of high-quality single crystals of layered Pd$…
