Unconventional Superconductivity in the Chiral Topological Semimetal Ag2Pd3S
Roshan Kumar Kushwaha, Dibyendu Samanta, Sudarshan Sharma +15
Chiral crystals provide a unique setting where broken inversion symmetry, strong spin-orbit coupling, and electronic topology intertwine, yet superconductivity in intrinsically chi…
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…
Topological and Planar Hall Effect in Monoclinic van der Waals Ferromagnet NbFeTe
Suchanda Mondal, Shubhankar Roy, Poulami Manna +1
Two-dimensional (2D) van der Waals (vdW) ferromagnets have emerged as a critical class of quantum materials for next-generation, low-dimensional spintronic devices. In this study,…
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…
