Superconducting diode effect in multiphase superconductors

D Shaffer, DV Chichinadze, A Levchenko - Physical Review B, 2024 - APS
We identify a particular mechanism for the intrinsic superconducting diode effect (SDE) in
multiphase superconductors. Using a Ginzburg-Landau and a microscopic two-band model …

Hysteresis and chaos in anomalous Josephson junctions without capacitance

AA Mazanik, AE Botha, IR Rahmonov… - Physical Review Applied, 2024 - APS
Overdamped Josephson junctions usually do not exhibit chaotic behavior in their phase
dynamics, either because the phase-space dimension is less than 3 (as in the case of a …

Giant nonreciprocity of current-voltage characteristics of noncentrosymmetric superconductor–normal metal–superconductor junctions

T Liu, M Smith, AV Andreev, BZ Spivak - Physical Review B, 2024 - APS
We develop a theory of nonreciprocal current-voltage (IU) characteristics in
noncentrosymmetric superconductor-normal metal-superconductor junctions. We show that …

Anomalous Josephson diode effect in superconducting multilayers

AS Osin, A Levchenko, M Khodas - Physical Review B, 2024 - APS
In this study, we explore the Josephson current-phase relation within a planar diffuse
tunneling superconducting multilayer junction subjected to a parallel magnetic field. Our …

Superconducting diode effect in two-dimensional topological insulator edges and Josephson junctions

H Huang, T de Picoli, JI Väyrynen - arxiv preprint arxiv:2404.14566, 2024 - arxiv.org
The superconducting diode effect--the dependence of critical current on its direction--can
arise from the simultaneous breaking of inversion and time-reversal symmetry in a …

Planar Hall effect from superconducting fluctuations

L Attias, K Michaeli, M Khodas - Physical Review B, 2024 - APS
We investigate the planar Hall effect (PHE) in two-dimensional (2D) superconductors with
spin-orbit interactions, where transport anisotropy is induced by an in-plane magnetic field …

Dissipative mechanisms in SNS junctions and magnetic vortex lattices

Y Liu - 2024 - search.proquest.com
When a normal metal is subject to an external field and a transport current is induced, the
dissipation rate is typically controlled by the elastic scattering time of the quasiparticles. In …
