Density-matrix quantum kinetics of spin-mode crossover and ac Edelstein response in spin--orbit-coupled chiral metals
Shuntaro Sumita, Yusuke Kato
To clarify spin relaxation and precession across the weak-to-strong SOC crossover in chiral conductors, we formulate a density-matrix quantum kinetic theory for a three-dimensional…
Fluctuation-induced antiparallel spin polarization near the boundaries of chiral metals
Kosuke Yoshimi, Yusuke Kato, Yuta Suzuki +4
The spin response of chiral conductors to nonequilibrium electrical fluctuations remains largely unexplored. We develop a low-frequency semiclassical Boltzmann theory coupled to Ga…
Theory of Magnetic Excitations in the Heavy-Fermion Spin-Triplet Superconductor UTe
Koki Shimura, Shuntaro Sumita, Yusuke Kato
We study the dynamical spin response of UTe by using a mixed-dimensional periodic Anderson model. Within the BCS-RPA formalism, we examine how the -orbital character of the…
Boundary condition for phonon distribution functions at a smooth crystal interface and interfacial angular momentum transfer
Yuta Suzuki, Shuntaro Sumita, Yusuke Kato
We theoretically elucidate the boundary conditions for phonon distribution functions of long-wavelength acoustic phonons at smooth crystal interfaces. We first derive boundary cond…
