Quantum transport and spin dynamics on shearless tori
K. Kudo, T. S. Monteiro
We investigate for quantum dynamics in phase-space regions containing ``shearless tori''. We show that the properties of these peculiar classical phase-space structures -- importan…
Dynamical stability for finite quantum spin chains against a time-periodic inhomogeneous perturbation
Kazue Kudo, Katsuhiro Nakamura
We investigate dynamical stability of the ground state against a time-periodic and spatially-inhomogeneous magnetic field for finite quantum XXZ spin chains. We use the survival pr…
Effects of an oscillating field on pattern formation in a ferromagnetic thin film: Analysis of patterns traveling at a low velocity
Kazue Kudo, Katsuhiro Nakamura
Magnetic domain patterns under an oscillating field is studied theoretically by using a simple Ising-like model. We propose two ways to investigate the effects of the oscillating f…
Field sweep rate dependence of magnetic domain patterns: Numerical simulations for a simple Ising-like model
Kazue Kudo, Katsuhiro Nakamura
We study magnetic domain patterns in ferromagnetic thin films by numerical simulations for a simple Ising-like model. Magnetic domain patterns after quench demonstrate various type…
