Nonequilibrium Fractional Josephson Effect

Quasiparticle trapping in quench dynamics of superconductor/quantum dot/superconductor Josephson junctions

J Cheng, X Zuo, J Wang, Y Xing - Physical Review B, 2024 - APS
With the aid of Keldysh nonequilibrium Green's functions, we investigate the quench
dynamics in a superconductor–quantum dot–superconductor (S-QD-S) Josephson junction …

Josephson Signatures of the Superconducting Higgs/Amplitude Mode

A Lahiri, SJ Choi, B Trauzettel - arXiv preprint arXiv:2402.13074, 2024 - arxiv.org
The Higgs/amplitude collective mode in superconductors corresponds to oscillations of the
amplitude of the order parameter. While its detection typically relies on optical techniques …

Interedge backscattering in time-reversal symmetric quantum spin Hall Josephson junctions

C Heinz, P Recher, F Dominguez - arXiv preprint arXiv:2410.12357, 2024 - arxiv.org
Using standard tight-binding methods, we investigate a novel backscattering mechanism
taking place on quantum spin Hall N'SNSN'Josephson junctions in the presence of time …
