Gyrotropic Fingerprints of Magnetic Topological Insulator-Unconventional Magnet Interfaces
Neelanjan Chakraborti, Snehasish Nandy, Sudeep Kumar Ghosh
Unambiguously identifying unconventional magnetic orders requires probes directly sensitive to their momentum-dependent spin-split band structures. Here, we employ a Zeeman quantum…
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,…
Zeeman Quantum Geometry as a Probe of Unconventional Magnetism
Neelanjan Chakraborti, Sudeep Kumar Ghosh, Snehasish Nandy
Unconventional magnets with momentum-dependent spin-splitting but zero net magnetization form a recently identified class of collinear magnets that are challenging to probe via con…
Field-free Superconducting Diode Effect and Topological Fulde-Ferrell Superconductivity in Altermagnetic Shiba Chains
Dibyendu Samanta, Sudeep Kumar Ghosh
The superconducting diode effect (SDE), characterized by a directional asymmetry in the critical supercurrents, typically requires external magnetic fields to break time-reversal s…
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…
Spectral Bifurcation and Anomalous Supercurrent in Dissipative Topological Insulator-based Josephson Junctions
Ardamon Sten, Paramita Dutta, Sudeep Kumar Ghosh
The interplay between topological protection and dissipation constitutes a critical frontier in the realization of hybrid quantum devices. Here, we investigate the transport signat…
