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…
Planar Josephson junction devices with narrow superconducting strips: Topological properties and optimization
Purna P. Paudel, Javad Shabani, Tudor D. Stanescu
We study the low-energy physics of planar Josephson junction structures realized in a quasi-two dimensional semiconductor system proximity-coupled to narrow superconducting films.…
Disorder effects in planar semiconductor-superconductor structures: Majorana wires versus Josephson junctions
Purna P. Paudel, Nathan O. Smith, Tudor D. Stanescu
Disorder effects in hybrid semiconductor-superconductor (SM-SC) nanowires, widely recognized as the main obstacle to realizing stable Majorana zero modes (MZMs) in these structures…
Proximity-induced superconductivity generated by thin films: Effects of Fermi surface mismatch and disorder in the superconductor
Tudor D. Stanescu, Sankar Das Sarma
We investigate the effects of disorder characterising a superconducting thin film on the proximity-induced superconductivity generated by the film (in, e.g., a semiconductor) based…
Dimensional crossover in spin-orbit-coupled semiconductor nanowires with induced superconducting pairing
Tudor D. Stanescu, Roman M. Lutchyn, S. Das Sarma
We show that the topological Majorana modes in nanowires much longer than the superconducting coherence length are adiabatically connected with discrete zero-energy states generica…
Topologically non-trivial superconductivity in spin-orbit coupled systems: Bulk phases and quantum phase transitions
Sumanta Tewari, Tudor D. Stanescu, Jay D. Sau +1
Topologically non-trivial superconductivity has been predicted to occur in superconductors with a sizable spin-orbit coupling in the presence of an external Zeeman splitting. Two s…
