Robust Vortex Lines, Vortex Rings and Hopfions in 3D Bose-Einstein Condensates
R. N. Bisset, Wenlong Wang, C. Ticknor +4
Performing a systematic Bogoliubov-de Gennes spectral analysis, we illustrate that stationary vortex lines, vortex rings and more exotic states, such as hopfions, are robust in thr…
Population annealing: Theory and application in spin glasses
Wenlong Wang, Jonathan Machta, Helmut G. Katzgraber
Population annealing is an efficient sequential Monte Carlo algorithm for simulating equilibrium states of systems with rough free energy landscapes. The theory of population annea…
On the Bifurcation and Stability of Single and Multiple Vortex Rings in Three-Dimensional Bose-Einstein Condensates
Russell Bisset, Wenlong Wang, C. Ticknor +4
In the present work, we investigate how single- and multi-vortex-ring states can emerge from a planar dark soliton in three-dimensional (3D) Bose-Einstein condensates (confined in…
Simulating thermal boundary conditions of spin-lattice models with weighted averages
Wenlong Wang
Thermal boundary conditions has played an increasingly important role in revealing the nature of short-range spin glasses and is likely to be relevant also for other disordered sys…
Stabilization of ring dark solitons in Bose-Einstein condensates
Wenlong Wang, P. G. Kevrekidis, R. Carretero-Gonzalez +3
Earlier work has shown that ring dark solitons in two-dimensional Bose-Einstein condensate are generically unstable. In this work, we propose a way of stabilizing the ring dark sol…
Chaos in spin glasses revealed through thermal boundary conditions
Wenlong Wang, Jon Machta, Helmut G. Katzgraber
We study the fragility of spin glasses to small temperature perturbations numerically using population annealing Monte Carlo. We apply thermal boundary conditions to a three-dimens…
Measuring free energy in parallel tempering Monte Carlo
Wenlong Wang
An efficient approach of measuring the absolute free energy in parallel tempering Monte Carlo using the exponential averaging method is discussed and the results are compared with…
