Two-dimensional epitaxial superconductor-semiconductor heterostructures: A platform for topological superconducting networks
J. Shabani, M. Kjaergaard, H. J. Suominen +12
Progress in the emergent field of topological superconductivity relies on synthesis of new material combinations, combining superconductivity, low density, and spin-orbit coupling…
Detection of Majorana Kramers pairs using a quantum point contact
Jian Li, Wei Pan, B. Andrei Bernevig +1
We propose a setup that integrates a quantum point contact (QPC) and a Josephson junction on a quantum spin Hall sample, experimentally realizable in InAs/GaSb quantum wells. The c…
Optimizing spin-orbit splittings in InSb Majorana nanowires
Alexey A. Soluyanov, Dominik Gresch, Roman M. Lutchyn +3
Semiconductor-superconductor heterostructures represent a promising platform for the detection of Majorana zero modes and subsequently the processing of quantum information using t…
Topological superconductivity in a multichannel Yu-Shiba-Rusinov chain
Junhua Zhang, Younghyun Kim, E. Rossi +1
Chains of magnetic atoms placed on the surface of an s-wave superconductor with large spin-orbit coupling provide a promising platform for the realization of topological supercondu…
Majorana zero modes choose Euler numbers - revealed by full counting statistics
Dong E. Liu, Alex Levchenko, Roman M. Lutchyn
We study transport properties of a quantum dot coupled to a Majorana zero mode and two normal leads. We investigate the full counting statistics of charge tunneling events which al…
Fractional Josephson Effect in Number-Conserving Systems
Meng Cheng, Roman M. Lutchyn
We study fractional Josephson effect in a particle-number conserving system consisting of a quasi-one-dimensional superconductor coupled to a nanowire or an edge carrying fra…
