Accurate ground-state entropies from population Monte Carlo: The antiferromagnetic Ising model on the Shastry-Sutherland lattice
Denis Gessert, Wolfhard Janke, Martin Weigel
We demonstrate how the population annealing Monte Carlo simulation method can be used to compute the ground-state entropy to high precision. This approach is tested for the classic…
Meandering stripes in the frustrated - Ising model on the honeycomb lattice
Denis Gessert, Martin Weigel, Wolfhard Janke
We study the frustrated - Ising model on the honeycomb lattice with ferromagnetic nearest-neighbor couplings fixed at and strong antiferromagnetic next-nearest-ne…
Frustrated Ising model on the honeycomb lattice: Metastability and universality
Denis Gessert, Martin Weigel, Wolfhard Janke
We study the Ising model with competing ferromagnetic nearest- and antiferromagnetic next-nearest-neighbor interactions of strengths and , respectively, on the h…
Partition function zeros of the frustrated - Ising model on the honeycomb lattice
Denis Gessert, Martin Weigel, Wolfhard Janke
We study the zeros of the partition function in the complex temperature plane (Fisher zeros) and in the complex external field plane (Lee-Yang zeros) of a frustrated Ising model wi…
Aging following a zero-temperature quench in the Ising model
Denis Gessert, Henrik Christiansen, Wolfhard Janke
Aging in phase-ordering kinetics of the Ising model following a quench from infinite to zero temperature is studied by means of Monte Carlo simulations. In this model the two…
Optimized population Monte Carlo
P. L. Ebert, D. Gessert, W. Janke +1
Population Monte Carlo simulations in the form commonly referred to as population annealing can serve as a useful meta-algorithm for simulating systems with complex free-energy lan…
Superdiffusion-like behavior in zero-temperature coarsening of the Ising model
Denis Gessert, Henrik Christiansen, Wolfhard Janke
One key aspect of coarsening following a quench below the critical temperature is domain growth. For the non-conserved Ising model a power-law growth of domains of like spins with…
Resampling schemes in population annealing: Numerical and theoretical results
Denis Gessert, Wolfhard Janke, Martin Weigel
The population annealing algorithm is a population-based equilibrium version of simulated annealing. It can sample thermodynamic systems with rough free-energy landscapes more effi…
Weighted averages in population annealing: analysis and general framework
Paul L. Ebert, Denis Gessert, Martin Weigel
Population annealing is a powerful sequential Monte Carlo algorithm designed to study the equilibrium behavior of general systems in statistical physics through massive parallelism…
Resampling schemes in population annealing -- numerical results
Denis Gessert, Martin Weigel, Wolfhard Janke
Population annealing (PA) is a population-based algorithm that is designed for equilibrium simulations of thermodynamic systems with a rough free energy landscape. It is known to b…
