The phenomenon of non-reciprocal critical current in a Josephson device, termed the
Josephson diode effect, has garnered much recent interest. Realization of the diode effect …

In hybrid Josephson junctions with three or more superconducting terminals coupled to a
semiconducting region, Andreev bound states may form unconventional energy band …

The Josephson junction (JJ) is an essential element of superconducting (SC) devices for
both fundamental and applied physics. The short-range coherent coupling of two adjacent …

We introduce Weyl Josephson circuits: small Josephson junction circuits that simulate Weyl
