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

We propose an efficient microscopic design procedure of electronic band structures having
intrinsic spin and momentum dependences in spin-orbit-coupling free antiferromagnets. Our …

Four types of atomic-scale multipoles (electric, magnetic, magnetic toroidal, and electric
toroidal multipoles) give a complete set to describe arbitrary degrees of freedom for coupled …

It is commonly believed that, in the absence of disorder or an external magnetic field, there
are three possible types of superconducting excitation gaps: The gap is nodeless, it has …

BiS2-based layered superconductors have attracted considerable interest owing to the
relatively large spin–orbit coupling of bismuth 6 p orbitals, the strong coupling nature by …

We present a comprehensive theory for Bogoliubov Fermi surfaces in inversion-symmetric
superconductors which break time-reversal symmetry. A requirement for such a gap …

We propose a generalization of the concept of superconducting fitness, which allows us to
make statements analogous to Anderson's theorems concerning the stability of different …

The exceptionally low-symmetry crystal structures of the time-reversal symmetry-breaking
superconductors LaNiC 2 and LaNiGa 2 lead to an internally antisymmetric nonunitary triplet …

Recent superconducting gap classifications based on space group symmetry have revealed
nontrivial gap structures that were not shown by point group symmetry. First, we review a …

Recent development in exact classification of a superconducting gap has elucidated various
unconventional gap structures, which have not been predicted by the classification of order …
