Asymptotic forms and scaling properties of the relaxation time near threshold points in spinodal-type dynamical phase transitions
Takashi Mori, Seiji Miyashita, Per Arne Rikvold
We study critical properties of the relaxation time at a threshold point in switching processes between bistable states under change of external fields. In particular, we investiga…
Intrinsic effects of the boundary condition on switching processes in spin-crossover solids
Masamichi Nishino, Cristian Enachescu, Seiji Miyashita +2
We investigated domain growth in switching processes between the low-spin and high-spin phases in thermally induced hysteresis loops of spin-crossover (SC) solids. Elastic interact…
Nagaoka ferromagnetism in large-spin systems -Fermion and Boson systems--
Seiji Miyashita, Masao Ogata, Hans De Raedt
We study magnetic properties of itinerant quantum magnetic particles described by a generalized Hubbard model with large spin () which may be realized in optical lattices of…
Comparison among Various Expressions of Complex Admittance for Quantum System in Contact with Heat Reservoir
Mizuhiko Saeki, Chikako Uchiyama, Takashi Mori +1
Relation among various expressions of the complex admittance for quantum systems in contact with heat reservoir is studied. Exact expressions of the complex admittance are derived…
Quantum Annealing for Variational Bayes Inference
Issei Sato, Kenichi Kurihara, Shu Tanaka +2
This paper presents studies on a deterministic annealing algorithm based on quantum annealing for variational Bayes (QAVB) inference, which can be seen as an extension of the simul…
Quantum Annealing for Clustering
Kenichi Kurihara, Shu Tanaka, Seiji Miyashita
This paper studies quantum annealing (QA) for clustering, which can be seen as an extension of simulated annealing (SA). We derive a QA algorithm for clustering and propose an anne…
