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…
Nonsymmorphic symmetry protected hourglass Dirac chain topology and conventional superconductivity in ZrIrGe
Pavan Kumar Meena, Dibyendu Samanta, Shashank Srivastava +3
Ternary transition-metal germanide superconductors with nonsymmorphic symmetries offer promising platforms for symmetry-protected topological phases. In this work, we investigate Z…
Field-free superconducting diode effect in two-dimensional Shiba lattices
Sayak Bhowmik, Dibyendu Samanta, Ashis K. Nandy +2
The superconducting diode effect (SDE) refers to non-reciprocal transport, where current flows without resistance in one direction but becomes resistive in the opposite direction,…
Topological superconductivity in hourglass Dirac chain metals (Ti, Hf)IrGe
Pavan Kumar Meena, Dibyendu Samanta, Sonika Jangid +5
Realizing topological superconductivity in stoichiometric materials is a key challenge in condensed matter physics. Here, we report the discovery of ternary germanide superconducto…
