Distinguishing Quantum Capacitance Signatures of a Topological Majorana Wire from a Normal Wire Segment
Binayyak Bhusan Roy, Jay Deep Sau, Sumanta Tewari
Majorana zero modes (MZMs) are spatially separated, near-zero-energy excitations expected at the ends of a topological superconducting (TS) wire. A quantum-dot interferometer can b…
MEDA: Measurement-Efficient Disorder-Aware Majorana Zero Mode Detection in Realistic Devices
Nathan Jones, Binayyak Roy, Valentine Mohaugen +4
Fault-tolerant topological quantum computing relies on identifying Majorana zero modes (MZMs), but reliable detection in realistic devices remains challenging. Conventional topolog…
Floquet-Engineered Parity Anomaly Staircase in a Cold Atom Dirac Lattice
Binayyak Roy, Vito Scarola, Sumanta Tewari
We propose a Floquet-engineered cold atom realization of a parity anomaly inspired anomalous Hall staircase in a two dimensional -flux lattice. The effective model hosts massive…
Intrinsic anomalous thermal hall effect as a signature of quantum metric in d-wave altermagnets
Rishi G. Gopalakrishnan, Srimayi Korrapati, Sumanta Tewari
We investigate the intrinsic anomalous thermal Hall effect in d-wave altermagnets, where a transverse heat current is generated by a longitudinal temperature gradient in the absenc…
Quantum Inductance as a Phase-Sensitive Probe of Fermion Parity Switching in Majorana Nanowires
Binayyak B. Roy, Jay D. Sau, Sumanta Tewari
We study the flux-dependent quantum inductance of a one-dimensional (1D) semiconductor-superconductor (SM-SC) Majorana nanowire coupled to a quantum dot in an interferometric setup…
Pfaffian-based topological invariants for one dimensional semiconductor-superconductor heterostructures
Binayyak B. Roy, William B. Cason, Nimish Sharma +1
We review the Pfaffian-based topological invariants in one dimensional semiconductor-superconductor (SM-SC) nanowire heterostructures and clarify their validity in f…
