This review provides a theoretical basis for understanding the current-phase relation (CΦR)
for the stationary (dc) Josephson effect in various types of superconducting junctions. The …

Since the first days of high-T c superconductivity, the materials science and the physics of
grain boundaries in superconducting compounds have developed into fascinating fields of …

Nonreciprocal responses of noncentrosymmetric quantum materials attracted recent
intensive interests, which is essential for the rectification function in diodes. A recent …

For certain orientations of Josephson junctions between two px-wave or two d-wave
superconductors, the subgap Andreev bound states produce a 4π-periodic relation between …

Van-der-Waals assembly enables the fabrication of novel Josephson junctions featuring an
atomically sharp interface between two exfoliated and relatively twisted Bi 2 Sr 2 CaCu 2 O …

Twisted bilayers of high-T c cuprate superconductors have been argued to form topological
phases with spontaneously broken time reversal symmetry T for certain twist angles. A key …

Abstract Majorana fermions are spin-1/2 neutral particles that are their own antiparticles and
were initially predicted by Ettore Majorana in particle physics but their observation still …

Several recent experiments revealed a change of the sign of the first harmonic in the current-
phase relation of Josephson junctions (JJs) based on, eg, d-wave superconductors or JJs …

We study the Josephson effect in a superconductor-altermagnet-superconductor junction.
We find anomalous phenomena, including 0-π transition and multinodal current-phase …

The escape rate from the zero voltage state in a superconducting Josephson junction (JJ) is
determined by the temperature, but it saturates at low temperature due to macroscopic …
