Majorana corner modes appearing in two-dimensional second-order topological
superconductors have great potential applications for fault-tolerant topological quantum …

Intensive studies for more than three decades have elucidated multiple superconducting
phases and odd-parity Cooper pairs in a heavy fermion superconductor UPt 3. We identify a …

The recent measurement of the de Haas–van Alphen effect in the spin-triplet superconductor
UTe 2 [D. Aoki, J. Phys. Soc. Jpn. 91, 083704 (2022) 0031-9015 10.7566/JPSJ. 91.083704] …

We study two-dimensional noncentrosymmetric nodal superconductors under Zeeman field
and clarify the field-angle dependence of topological properties. It has been shown that the …

We study a dynamical spin response of surface Majorana modes in a topological
superconductor–magnet hybrid under microwave irradiation. We find a method to toggle …

In contrast to elementary Majorana particles, emergent Majorana fermions (MFs) in
condensed-matter systems may have electromagnetic multipoles. We developed a general …

We study the topology and symmetry of surface Majorana arcs in superconductors with
nonunitary “cyclic” pairing. Cyclic p-wave pairing may be realized in a cubic or tetrahedral …

We discuss the spin susceptibility of superconductors in which a Cooper pair consists of two
electrons having the angular momentum J= 3/2 due to strong spin–orbit interactions. The …

We investigate emergent odd-frequency pairs and proximity effect in nematic and chiral
states of superconducting topological insulators (STIs), such as M x Bi 2 Se 3 (M= Cu, Sr …

Whereas identification of Cooper-pair symmetry is the first and crucial step in the
investigation of unconventional superconductors, only a few have been established so far …
