Superconductivity and magnetism are adversarial states of matter. The presence of
spontaneous magnetic fields inside the superconducting state is, therefore, an intriguing …

The most well-known example of an ordered quantum state—superconductivity—is caused
by the formation and condensation of pairs of electrons. Fundamentally, what distinguishes …

Abstract Strontium ruthenate (Sr2RuO4) continues to present an important test of our
understanding of unconventional superconductivity, because while its normal-state …

The recently discovered superconductivity with critical temperature T c up to 80 K in the
double-layer Nickelate La 3 Ni 2 O 7-δ under pressure has drawn great attention. Here, we …

Recent work done on the time reversal symmetry (TRS) breaking superconductors is
reviewed in this paper. The special attention is paid to Sr 2 RuO 4 believed to be spin triplet …

Over the past years a lot of theoretical and experimental effort has been made to find states
with broken time-reversal symmetry (BTRS) in multiband superconductors. In particular, it …

Gate-controlled supercurrent (GCS) in superconducting nanobridges has recently attracted
attention as a means to create superconducting switches. Despite the clear advantages for …

The Th 7 Fe 3 family of superconductors provides a rich playground for unconventional
superconductivity. La 7 Ni 3 is the latest member of this family, which we here investigate by …

The single helical Fermi surface on the surface state of three-dimensional topological
insulator Bi 2 Se 3 is constrained by the time-reversal invariant bulk topology to possess a …

Among unconventional superconductors, Sr $ _2 $ RuO $ _4 $ has become a benchmark
for experimentation and theoretical analysis because its normal-state electronic structure is …
