The repulsive Hubbard model has been immensely useful in understanding strongly
correlated electron systems and serves as the paradigmatic model of the field. Despite its …

A superconducting diode enables supercurrent to flow in only one direction, providing new
functionalities for superconducting circuits. In recent years, there has been experimental …

Moiré quantum matter has emerged as a materials platform in which correlated and
topological phases can be explored with unprecedented control. Among them, magic-angle …

The critical current of a superconductor can be different for opposite directions of current flow
when both time-reversal and inversion symmetry are broken. Such non-reciprocal behaviour …

This paper reviews recent experimental and theoretical progress concerning many-body
phenomena in dilute, ultracold gases. It focuses on effects beyond standard weak-coupling …

Majorana fermions are predicted to localize at the edge of a topological superconductor, a
state of matter that can form when a ferromagnetic system is placed in proximity to a …

Stimulated by the recent experiment [F. Ando, Nature (London) 584, 373 (2020). NATUAS
0028-0836 10.1038/s41586-020-2590-4], we propose an intrinsic mechanism to cause the …

When both inversion and time-reversal symmetries are broken, the critical current of a
superconductor can be nonreciprocal. In this work, we show that, in certain classes of two …

A previously obtained solution of the linearized Gor'kov equations for the upper critical
magnetic field H c 2 of a bulk type-II superconductor is extended to include the effects of …

The proximity effect at superconductor-ferromagnet interfaces produces damped oscillatory
behavior of the Cooper pair wave function within the ferromagnetic medium. This is …
