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 …

This topical review summarizes various features of magnetic penetration depth in
unconventional superconductors. Precise measurements of the penetration depth as a …

Spin-orbit coupling in two-dimensional systems is usually characterized by Rashba and
Dresselhaus spin-orbit coupling (SOC) linear in the wave vector. However, there is a …

This review is an up-to-date snapshot of the current situation in studies of materials with
competing electron spectrum instabilities, namely Cooper pairing, on the one hand, and …

This review deals with the properties of superconductors with competing electron spectrum
instabilities, namely, charge-density waves (CDWs) and spin-density waves (SDWs). The …

We prepared atomically clean Bi 2 Sr 2 CaCu 2 O 8+ δ Josephson junctions between
identical single crystal cleaves stacked and twisted an angle φ 0 about the c axis. For each …

Theoretical and experimental work concerning high-temperature superconductors in
general and cuprates in particular is reviewed. A detailed analysis of the current knowledge …

A pivotal step toward understanding unconventional superconductors would be to decipher
how superconductivity emerges from the unusual normal state. In the cuprates, traces of …

The aim of this review is to summarize existing experimental investigations on the nature of
the low-energy quasiparticle excitations in high-T c cuprates, and to examine critically recent …

We investigated the nonlinear Meissner effect (NLME) in Nb 3 Sn thin-film coplanar
resonators by measuring the resonance frequency as a function of a parallel magnetic field …
