Anisotropic heat conduction of coherently transported phonons in InGaO3(ZnO)m single crystal films with superlattice structures
Hai Jun Cho, Yuzhang Wu, Youngha Kwon +4
Superlattices provide a great platform for studying coherent transportation of low-frequency phonons, which are the main issues in mastering the manipulation of heat conduction. St…
Transport anomaly in the low energy regime of spin chains
Keiji Saito
The anomalous thermal conductivity in spin chains observed in experiments is studied for the low temperature regime. In the effective dynamics with most realistic perturbations, th…
Enhancement of the Thermal Conductivity in gapped Quantum Spin Chains
Keiji Saito, Seiji Miyashita
We study mechanism of magnetic energy transport, motivated by recent measurements of the thermal conductivity in low dimensional quantum magnets. We point out a possible mechanism…
Nonexponential Relaxation of Magnetization at the Resonant Tunneling Point under a Fluctuating Random Noise
Seiji Miyashita, Keiji Saito
Nonexponential relaxation of magnetization at resonant tunneling points of nanoscale molecular magnets is interpreted to be an effect of fluctuating random field around the applied…
Magnetic Foehn Effect in Nonadiabatic Transition
Keiji Saito, Seiji Miyashita
The magnetization curves as a response of sweeping magnetic field in the thermal environment are investigated using the quantum master equation. In a slow velocity region where the…
Quantum Dynamics in Nanoscale Magnets in Dissipative Environments
Seiji Miyashita, Keiji Saito, Hiroto Kobayashi +1
In discrete energy structure of nanoscale magnets, nonadiabatic transitions at avoided level crossings lead to fundamental processes of dynamics of magnetizations. The thermal envi…
