Pairing symmetry in the cuprate superconductors is an important and controversial topic.
The recent development of phase-sensitive tests, combined with the refinement of several …

Twisted interfaces between stacked van der Waals (vdW) cuprate crystals present a platform
for engineering superconducting order parameters by adjusting stacking angles. Using a …

Stacking two-dimensional van der Waals (vdW) materials rotated with respect to each other
show versatility for studying exotic quantum phenomena. In particular, anisotropic layered …

Many superconducting systems with broken time-reversal and inversion symmetry show a
superconducting diode effect, a non-reciprocal phenomenon analogous to semiconducting …

Current-voltage characteristics in the c-axis direction were studied experimentally for small-
area Bi 2 Sr 2 CaCu 2 O 8+ x mesas containing only a few intrinsic stacked Josephson …

We study the influence of dissipation on the switching current statistics of moderately
damped Josephson junctions. Different types of both low-and high-T c junctions with …

We present a systematic numerical study of the coupled one-dimensional sine-Gordon
equations for a stack of 20 Josephson junctions, with junction parameters that are …

We fabricated small-size stacks on the surface of Bi 2 Sr 2 CaCu 2 ZO 8+ x single crystals
with the bulk transition temperature T c≃ 90 K, each containing a few intrinsic Josephson …

We study arrays of planar Nb Josephson junctions with contacts to intermediate electrodes,
which allow measurements of individual junctions and, thus, provide an insight into intricate …

Cascade multiplication is a common technique to enhance the sensitivity of photon
detectors. In this study, we demonstrate novel cascade-amplified superconducting detectors …
