Josephson wormhole in coupled superconducting Yukawa-SYK metals
Aravindh S. Shankar, Jasper Steenbergen, Stephan Plugge +1
We show that two Yukawa-SYK models with a weak tunneling contact can have an exotic hybrid superconducting thermofield-double-like state that is holographically dual to a traversab…
Josephson diode effects in twisted nodal superconductors
Pavel A. Volkov, Étienne Lantagne-Hurtubise, Tarun Tummuru +3
Recent Josephson tunneling experiments on twisted flakes of high- cuprate superconductor BiSrCaCuO revealed a non-reciprocal behavior of the critical inter…
Magnus effect on a Majorana zero-mode
G. Lemut, M. J. Pacholski, S. Plugge +2
A supercurrent on the proximitized surface of a topological insulator can cause a delocalization transition of a Majorana fermion bound to a vortex core as a zero-mode. Here we stu…
Lyapunov exponents in a Sachdev-Ye-Kitaev-type model with population imbalance in the conformal limit and beyond
A. S. Shankar, M. Fremling, S. Plugge +1
The Sachdev-Ye-Kitaev (SYK) model shows chaotic behavior with a maximal Lyapunov exponent. In this paper, we investigate the four-point function of a SYK-type model numerically, wh…
Josephson effects in twisted cuprate bilayers
Tarun Tummuru, Stephan Plugge, Marcel Franz
Twisted bilayers of high- cuprate superconductors have been argued to form topological phases with spontaneously broken time reversal symmetry for certain twist ang…
Emergent Interfacial Superconductivity between Twisted Cuprate Superconductors
S. Y. Frank Zhao, Nicola Poccia, Xiaomeng Cui +11
Twisted interfaces between stacked van der Waals cuprate crystals enable tunable Josephson coupling between in-plane anisotropic superconducting order parameters. Employing a novel…
