Critical Universality of the SU (2) Gauge Glass Model Analyzed by the Dynamical Scaling Method
Yosei Takada, Yusuke Terasawa, Yuma Osada +1
We investigate the critical phenomena of the three-dimensional (3D) gauge glass model, which can be regarded as the spin-glass model with gauge symmetry. Using Monte…
Dynamical scaling method improved by a deep learning approach
Yusuke Terasawa, Yukiyasu Ozeki
We propose a dynamical scaling analysis improved by a deep learning approach. While Gaussian process regression has been widely employed for estimating scaling parameters, its comp…
Dynamical scaling study for the estimation of dynamical exponent of three-dimensional XY spin glass model
Yusuke Terasawa, Yukiyasu Ozeki
To analyze the XY spin-glass in three dimensions, we verified a method aimed at obtaining a high-precision dynamical exponent from the correlation length in the nonequi…
Improvement of analysis for relaxation of fluctuations by the use of Gaussian process regression and extrapolation method
Yuma Osada, Yukiyasu Ozeki
The nonequilibrium relaxation (NER) method, which has been used to investigate equilibrium systems via their nonequilibrium behavior, has been widely applied to various models to e…
Gauge Theory for Quantum Spin Glasses
Satoshi Morita, Yukiyasu Ozeki, Hidetoshi Nishimori
The gauge theory for random spin systems is extended to quantum spin glasses to derive a number of exact and/or rigorous results. The transverse Ising model and the quantum gauge g…
Dynamical Gauge Theory for the XY Gauge Glass Model
Yukiyasu Ozeki
Dynamical systems of the gauge glass are investigated by the method of the gauge transformation.Both stochastic and deterministic dynamics are treated. Several exact relations are…
Energy fluctuations at the multicritical point in two-dimensional spin glasses
Hidetoshi Nishimori, Cyril Falvo, Yukiyasu Ozeki
We study the two-dimensional +/-J Ising model, three-state Potts model and four-state Potts model, by the numerical transfer matrix method to investigate the behaviour of the sampl…
Aging Relation for Ising Spin Glasses
Yukiyasu Ozeki
We derive a rigorous dynamical relation on aging phenomena -- the aging relation -- for Ising spin glasses using the method of gauge transformation. The waiting-time dependence of…
Ground-State Phase Diagrams of the Two-Dimensional Quantum Heisenberg Spin Glass Models
Yoshihiko Nonomura, Yukiyasu Ozeki
Ground-state properties of the two-dimensional random Heisenberg models are investigated by the exact-diagonalization method. The phase diagram of the bond-random model (th…
Long-Range Order of the Site-Random Spin Glass Model
Yukiyasu Ozeki, Yoshihiko Nonomura
The site-random Ising spin glass model is investigated. We find a rigorous symmetry for the SG correlation and the free energy, which provides some restrictions in the phase diagra…
