A strategy for solving difficulties in spin-glass simulations
Tota Nakamura
A spin-glass transition has been investigated for a long time but we have not yet reached a conclusion due to difficulties in the simulations. They are slow dynamics, strong finite…
Quantum-thermal annealing with cluster-flip algorithm
Satoshi Morita, Sei Suzuki, Tota Nakamura
A quantum-thermal annealing method using a cluster-flip algorithm is studied in the two-dimensional spin-glass model. The temperature (T) and the transverse field (Gamma) are decre…
Dynamic crossover in the spin-glass phase
Tota Nakamura
Dynamic scaling analyses are performed in the spin-glass phase of the Ising, the {\it XY}, and the Heisenberg models in three dimensions. We found a crossover from the crit…
Nonequilibrium dynamic exponent and spin-glass transitions
Tota Nakamura
Nonequilibrium dynamics of the Ising, the {\it XY}, and the Heisenberg spin-glass models are investigated in three dimensions. A nonequilibrium dynamic exponent is calculat…
Finite spin-glass transition of the XY model in three dimensions
Takeo Yamamoto, Takeshi Sugashima, Tota Nakamura
A three-dimensional XY spin-glass model is investigated by a nonequilibrium relaxation method. We have introduced a new criterion for the finite-time scaling analysis. A tr…
Uniform Magnetic Order in a Ferromagnetic-Antiferromagnetic Random Alternating Quantum Spin Chain
Tota Nakamura
An ferromagnetic (F) - antiferromagnetic (AF) random alternating Heisenberg quantum spin chain model is investigated in connection to its realization compound: (CH)…
