Defects and their Time Scales in Quantum and Classical Annealing of the Two-Dimensional Ising Model
Phillip Weinberg, Na Xu, Anders W. Sandvik
We investigate defects in the two-dimensional transverse-field Ising ferromagnet on periodic lattices after quantum annealing from high to vanishing field. With exact n…
Dynamic scaling of topological ordering in classical systems
Na Xu, Claudio Castelnovo, Roger G. Melko +2
We analyze scaling behaviors of simulated annealing carried out on various classical systems with topological order, obtained as appropriate limits of the toric code in two and thr…
Dynamic scaling in the 2D Ising spin glass with Gaussian couplings
Na Xu, Kai-Hsin Wu, Shanon J. Rubin +2
We carry out simulated annealing and employ a generalized Kibble-Zurek scaling hypothesis to study the 2D Ising spin glass with normal-distributed couplings. The system has an equi…
Modulated phases in a three-dimensional Maier-Saupe model with competing interactions
P. F. Bienzobaz, Na Xu, Anders W. Sandvik
This work is dedicated to the study of the discrete version of the Maier-Saupe model in the presence of competing interactions. The competition between interactions favoring differ…
Dual time scales in simulated annealing of a two-dimensional Ising spin glass
Shanon J. Rubin, Na Xu, Anders W. Sandvik
We apply a generalized Kibble-Zurek out-of-equilibrium scaling ansatz to simulated annealing when approaching the spin-glass transition at temperature of the two-dimensional…
