Nature of the phase transition of the three-dimensional isotropic Heisenberg spin glass
K. Hukushima, H. Kawamura
Equilibrium properties of the three-dimensional isotropic Heisenberg spin glass are studied by extensive Monte Carlo simulations, with particular attention to the nature of its pha…
Aging Effect in Ceramic Superconductors
Mai Suan Li, Per Nordblad, Hikaru Kawamura
A three-dimensional lattice of the Josephson junctions with a finite self-conductance is employed to model ceramic superconductors. Using Monte Carlo simulations it is shown that t…
Chiral order of Spin-1/2 frustrated quantum spin chains
T. Hikihara, M. Kaburagi, H. Kawamura
The ordering of the frustrated S=1/2 XY spin chain with the competing nearest- and next-nearest-neighbor antiferromagnetic couplings, J_1 and J_2, is studied by using the density-m…
How the Replica-Symmetry-Breaking Transition Looks Like in Finite-Size Simulations
K. Hukushima, H. Kawamura
Finite-size effects in the mean-field Ising spin glass and the mean-field three-state Potts glass are investigated by Monte Carlo simulations. In the thermodynamic limit, each mode…
Chiral-glass transition and replica symmetry breaking of a three-dimensional Heisenberg spin glass
K. Hukushima, H. Kawamura
Extensive equilibrium Monte Carlo simulations are performed for a three-dimensional Heisenberg spin glass with the nearest-neighbor Gaussian coupling to investigate its spin-glass…
Chiral Glass Phase in Ceramic Superconductors
Mai Suan Li, Hikaru Kawamura
A three-dimensional lattice of the Josephson junctions with a finite self-conductance is employed to model the ceramic superconductors. By Monte Carlo simulations it is shown that…
