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

A highly unconventional superconducting state with a spin-singlet $ d_ {x^ 2-y^ 2}\pm {\rm i}
d_ {xy} $-wave, or chiral d-wave symmetry has recently been suggested to emerge from …

We systematically study gapless topological phases of (semi-) metals and nodal
superconductors described by Bloch and Bogoliubov–de Gennes Hamiltonians. Using K …

Technological progress in material synthesis, as well as artificial realization of condensed
matter scenarios via ultra-cold atomic gases in optical lattices or epitaxial growth of thin …

Molybdenum disulphide (MoS 2) has attracted much interest in recent years due to its
potential applications in a new generation of electronic devices. Recently, it was shown that …

We report the magnetic and superconducting properties of locally noncentrosymmetric
SrPtAs obtained by muon-spin-rotation/relaxation (μ SR) measurements. Zero-field μ SR …

Recent muon spin-rotation (μ SR) measurements on SrPtAs revealed time-reversal-
symmetry breaking with the onset of superconductivity [Biswas, Phys. Rev. B 87, 180503 …

Van der Waals materials offer unprecedented control of electronic properties via stacking of
different types of two-dimensional materials. A fascinating frontier, largely unexplored, is the …

Stimulated by recent studies of quantum phases with broken local inversion symmetry, we
study the magnetoelectric effect in locally noncentrosymmetric metals. We consider three …

Determination of the symmetry property of superconducting gaps has been a central issue in
studies to understand the mechanisms of unconventional superconductivity. Although it is …
