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…
A First-Principles Multiscale Framework for Topological Superconductivity
Christopher L. Jacobs, Baishali Mandal, Taehwan Jung +4
A microscopic understanding of topological superconductivity (TSC) in real materials requires a materials-informed approach that integrates first-principles electronic structure, s…
Role of quantum confinement in semiconductor-superconductor core-shell nanowires
Tudor Gabriel Dumitru, Anna Sitek, Gunnar Thorgilsson +3
This work is motivated by the experimentally observed coherence of the supercurrent in semiconductor nanowires covered by a half-shell metallic superconductor, which leads to flux…
Topological invariant for finite systems in the presence of disorder
Robert Eissele, Binayyak B. Roy, Sumanta Tewari +1
Topological invariants, rigorously defined only in the thermodynamic limit, have been generalized to topological indicators applicable to finite-size disordered systems. However, i…
Rashba spin-orbit coupling and artificially engineered topological superconductors
Sankar Das Sarma, Katharina Laubscher, Haining Pan +2
One of the most important physical effects in condensed matter physics is the Rashba spin-orbit coupling (RSOC), introduced in seminal works by Emmanuel Rashba. In this article, we…
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…
