Superconductivity in structurally complex -Phase Re-X (X = V, Nb, Ta) and a derived medium-entropy alloys
Pavan Kumar Meena, Tomasz Klimczuk
The structurally complex tetragonal sigma ()-phase provides a unique platform for investigating the interplay between chemical disorder, electronic structure, and superconductiv…
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 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…
Observation of superconductivity in a nontrivial approximant quasicrystal
Pavan Kumar Meena, Rahul Verma, Arushi +6
Superconductivity and nontrivial topology are highly sought-after phenomena in quantum materials. While many topological crystalline materials have been found to exhibit supercondu…
Topological surface states host superconductivity induced by the bulk condensate in YRuB
Nikhlesh Singh Mehta, Bikash Patra, Mona Garg +8
While the possibility of topological superconductivity (TSC) in hybrid heterostructures involving topologically nontrivial band structure and superconductors has been proposed, the…
