Numerical study of metastability due to tunneling: The quantum string method
Tiezheng Qian, Weiqing Ren, Jing Shi +2
We generalize the string method, originally designed for the study of thermally activated rare events, to the calculation of quantum tunneling rates. This generalization is based o…
Convergence of Fine-lattice Discretization for Near-critical Fluids
Sarvin Moghaddam, Young C. Kim, Michael E. Fisher
In simulating continuum model fluids that undergo phase separation and criticality, significant gains in computational efficiency may be had by confining the particles to the sites…
Why spin ice obeys the ice rules
S. V. Isakov, R. Moessner, S. L. Sondhi
The low temperature entropy of the the spin ice compounds, such as HoTiO and DyTiO, is well described by the nearest-neighbor antiferromagnetic Ising model…
Magnetization process of spin ice in a [111] magnetic field
S. V. Isakov, K. S. Raman, R. Moessner +1
Spin ice in a magnetic field in the [111] direction displays two magnetization plateaux, one at saturation and an intermediate one with finite entropy. We study the crossovers betw…
Optimizing the ensemble for equilibration in broad-histogram Monte Carlo simulations
Simon Trebst, David A. Huse, Matthias Troyer
We present an adaptive algorithm which optimizes the statistical-mechanical ensemble in a generalized broad-histogram Monte Carlo simulation to maximize the system's rate of round…
On bipartite Rokhsar-Kivelson points and Cantor deconfinement
Eduardo Fradkin, David A. Huse, R. Moessner +2
Quantum dimer models on bipartite lattices exhibit Rokhsar-Kivelson (RK) points with exactly known critical ground states and deconfined spinons. We examine generic, weak, perturba…
