Proposing one-sided tetrons as topological qubits for Majorana-based quantum computation
Tudor D. Stanescu, Sumanta Tewari
One-dimensional SM-SC hybrid nanowires with Rashba spin-orbit coupling and applied Zeeman field can support Majorana zero modes (MZMs) at the ends of the wire. In finite-length sys…
Fermion parity and quantum capacitance oscillation with partially separated Majorana and quasi-Majorana modes
Tudor D. Stanescu, Sumanta Tewari
In a recent experiment, flux dependent oscillations of the quantum capacitance were observed in a one dimensional spin-orbit coupled semiconductor superconductor heterostructure co…
Topological superfluid phases of attractive Fermi-Hubbard model in narrow-band cold-atom optical lattices
T. D. Stanescu, Sumanta Tewari, V. W. Scarola
We investigate the effects of attractive Hubbard interaction on two-component fermionic atoms in narrow two-dimensional (2D) energy bands that exhibit Rashba spin-orbit coupling (S…
Stabilizing topological superconductivity in disordered spin-orbit coupled semiconductor-superconductor heterostructures
Binayyak B. Roy, Rimika Jaiswal, Tudor D. Stanescu +1
We investigate theoretically a one-dimensional semiconductor-superconductor (SM-SC) heterostructure with Rashba spin-orbit coupling and parallel Zeeman field in the presence of dis…
Nonlinear anomalous transverse responses induced by Berry curvature quadrupole in systems with broken time-reversal symmetry
Srimayi Korrapati, Snehasish Nandy, Sumanta Tewari
Recent theoretical work has shown that higher-order moments of the Berry curvature, e.g., Berry curvature quadrupole and hexapole moments, can produce the leading order nonlinear a…
Hydrogen induces chiral conduction channels in the topological magnet
Afrin N. Tamanna, Ayesha Lakra, Xiaxin Ding +7
Chirality, a characteristic handedness that distinguishes 'left' from 'right', cuts widely across all of nature, from the structure of DNA to opposite chirality of particle…
