Bloch Diode

Author(s): M. Houzet, T. Vakhtel, and J. S. Meyer The Josephson diode effect—an asymmetry of critical currents at opposite polarities—has attracted much attention recently. One of its simplest realizations is an asymmetric SQUID with multiple Josephson harmonics tuned away from half-integer flux (in units of the superconducting flux quantum). Here … [Phys. Rev.
