Superconducting diode effect in correlated electron systems by nonreciprocal magnetism
Kyohei Nakamura, Youichi Yanase
The superconducting diode effect (SDE), characterized by a nonreciprocal critical current in superconductors, has recently been observed in strongly correlated electron systems and…
Electron-Hole Scattering Dichotomy and Anisotropic Warping in Quasi-Two-Dimensional Fermi Surfaces of UTe2
Motoi Kimata, Jun Ishizuka, Freya Husstedt +13
We present a combined experimental and theoretical study of the detailed Fermi-surface (FS) geometry of UTe2, a heavy-fermion superconductor that has recently attracted considerabl…
Microwave Kerr/Faraday Resonance in Two-dimensional Chiral Superconductors
Taiki Matsushita, Jun'ichi Ieda, Yasufumi Araki +3
We investigate the polar Kerr and Faraday effects in two-dimensional multiband chiral superconductors. We show that the clapping modes--the relative phase and amplitude oscillation…
Intrinsic spin Nernst effect in spin-triplet superconductors
Taiki Matsushita, Youichi Yanase, Takeshi Mizushima +2
We theoretically investigate the intrinsic (impurity-independent) spin Nernst effect (SNE), a spin current generation perpendicular to temperature gradients, in spin-triplet superc…
Superconductivity in UTe from local noncentrosymmetricity
Ryuji Hakuno, Youichi Yanase
Superconductivity in UTe has garnered significant attention, as it is widely recognized as a promising candidate for a spin-triplet superconductor. However, the symmetry of s…
Supercurrent-induced antiferromagnetic order and spin-triplet pair generation in quantum critical d-wave superconductors
Kyohei Nakamura, Youichi Yanase
A supercurrent is well recognized as being of prime importance within mean-field theory, but remains largely unexplored in strongly correlated electron systems (SCES) and the quant…
