The disorder and interaction effects on Bogoliubov-Fermi surfaces with preserved inversion
symmetry are studied for a low-energy effective model coupled to bosonic degrees of …

The η-pairing is a type of Cooper pairing state in which the phase of the superconducting
order parameter is aligned in a staggered manner, in contrast to the usual BCS …

We study a superconductor Josephson junction with a Bogoliubov Fermi surface, employing
McMillan's Green's function technique. The low-energy degrees of freedom are described by …

Multipole representation is proposed for the anisotropic Coulomb interactions in solids. Any
local interactions can be expressed as the product of two multipole operators, and the …

We develop a theory describing spatiotemporal behavior of spin transport in two-band
metals by postulating a spin–exchange interaction between electrons and holes. Starting …

We analyze superconducting correlations in the one-dimensional Kondo lattice models with
Ising anisotropy under transverse magnetic fields, using the density matrix renormalization …

We theoretically study physical properties of the low-energy quasiparticle excitations at the
vortex core in the full-gap superconducting state of the Kondo lattice coupled to …

The coexistence of ferromagnetism and superconductivity has attracted considerable
attention since the discovery in UGe2. Since then, both experimental and theoretical studies …

Focusing on the superconducting state arising from two-channel Kondo effect in the non-
Kramers doublet system with semi-metallic conduction bands, we have studied the possible …
