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…
Systematic construction of asymptotic quantum many-body scar states and their relation to supersymmetric quantum mechanics
Masaya Kunimi, Yusuke Kato, Hosho Katsura
We develop a systematic method for constructing asymptotic quantum many-body scar (AQMBS) states. While AQMBS states are closely related to quantum many-body scar (QMBS) states, th…
Theory of phonon angular momentum transport across a smooth crystal interface
Yuta Suzuki, Shuntaro Sumita, Yusuke Kato
We theoretically elucidate the transfer of phonon angular momentum by acoustic modes across a smooth interface between crystals. We analyze this process, which is difficult to desc…
Chirality-dependent spin polarization in metals: linear and quadratic responses
Kosuke Yoshimi, Yusuke Kato, Yuta Suzuki +6
We study spin polarization induced by locally injected electric currents in a metal whose spin--orbit coupling reflects its structural chirality. We reveal both spin polarization i…
Anisotropy-induced spin parity effects
Shuntaro Sumita, Akihiro Tanaka, Yusuke Kato
Spin parity effects refer to those special situations where a dichotomy in the physical behavior of a system arises, solely depending on whether the relevant spin quantum number is…
