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 …

Persistent currents circulate continuously without requiring external power sources. Here,
we extend their theory to include dissipation within the framework of non-Hermitian quantum …

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

When a physical system is subjected to a strong external multifrequency drive, its dynamics
can be conveniently represented in the multidimensional Floquet lattice. The number of …

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 …

InSb, a narrow-band III-V semiconductor, is known for its small bandgap, small electron
effective mass, high electron mobility, large effective g-factor, and strong spin-orbit …

Weyl fermions have not been found in nature as elementary particles, but they emerge as
nodal points in the band structure of electronic and classical wave crystals. Novel …

We report a probable observation of the dc Josephson effect in mesoscopic junctions of
three and four superconductors. The devices are fabricated in a top-down fashion from a …

We demonstrate concomitant measurement of phase-dependent critical current and
Andreev bound state spectrum in a highly transmissive InAs Josephson junction embedded …

We introduce Weyl Josephson circuits: small Josephson junction circuits that simulate Weyl
band structures. We first formulate a general approach to design circuits that are analogous …
