Magnetization Process of Nanoscale Iron Cluster
Hiroki Nakano, Seiji Miyashita
Low-temperature magnetization process of the nanoscale iron cluster in linearly sweeped fields is investigated by a numerical analysis of time-dependent Schrdinger eq…
Programming physical realizations of quantum computers
Hans De Raedt, Kristel Michielsen, Anthony Hams +2
We study effects of the physical realization of quantum computers on their logical operation. Through simulation of physical models of quantum computer hardware, we analyze the dif…
Noise effect on the nonadiabatic transition and correction to the tunneling energy gap estimated by the Landau-Zener-Stuckelberg formula
Masamichi Nishino, Keiji Saito, Seiji Miyashita
We study effect of noise on the tunneling process of the magnetization in a sweeping field from the viewpoint of the nonadiabatic transition. The tunneling probability depends on t…
A microscopic mechanism for rejuvenation and memory effects in spin glasses
S. Miyashita, E. Vincent
Aging in spin glasses (and in some other systems) reveals astonishing effects of `rejuvenation and memory' upon temperature changes. In this paper, we propose microscopic mechanism…
