Superconducting ground state study of Cr-based equiatomic high-entropy alloy through
Sonika Jangid, Rhea Stewart, Adrian D. Hillier +1
High-entropy alloy superconductors, characterized by extreme chemical disorder and complex electronic environments, have attracted significant attention as model systems for explor…
Discovery of Quasi One Dimensional Superconductivity in PtPb3Bi
Shashank Srivastava, Yash Vardhan, Anshu Kataria +11
Quasi one dimensional materials provide a compelling platform where reduced dimensionality stabilizes intertwined topological and superconducting phases. Here we report superconduc…
Hourglass Dirac chains enable intrinsic topological superconductivity in nonsymmorphic silicides
Shashank Srivastava, Dibyendu Samanta, Pavan Kumar Meena +8
Nonsymmorphic crystalline symmetries provide a robust route to symmetry-protected electronic topology, yet their role in stabilizing intrinsic topological superconductivity remains…
Observation of Time-Reversal Symmetry Breaking in the Type-I Superconductor YbSb
Anshu Kataria, Shashank Srivastava, Dibyendu Samanta +9
The spontaneous breaking of time-reversal symmetry is a hallmark of unconventional superconductivity, typically observed in type-II superconductors. Here, we report evidence of tim…
Probing the intermediate state of type-I superconductor SnAs using Muon Spin Spectroscopy
Shashank Srivastava, Omkar Kulkarni, Arushi +8
Superconductivity with non-trivial band topology provides a novel platform for exploring topological superconductivity and its quantum applications. A detailed microscopic understa…
Measurement of production branching ratio after muon nuclear capture reaction of Al and Si isotopes
R. Mizuno, M. Niikura, T. Y. Saito +18
Background: Muon nuclear capture is a reaction between a muon and a proton inside a nucleus through weak interactions. This reaction results in the formation of an excited nucleus,…
