Supercurrent diode effect and finite-momentum superconductors.

Published in: Proceedings of the National Academy of Sciences of the United States of America (2022)

SignificanceOur work shows a fascinating application of finite-momentum superconductivity, the supercurrent diode effect, which is being reported in a growing number of experiments. We show that, under external magnetic field, Cooper pairs can acquire finite momentum so that critical currents in the direction parallel and antiparallel to the Cooper pair momentum become unequal.
