Stochastic motion under nonlinear friction representing shear thinning
Theo Lequy, Andreas M. Menzel
We study stochastic motion under a nonlinear frictional force that levels off with increasing velocity. Specifically, our frictional force is of the so-called Coulomb-tanh type. At…
Local interactions and non-Abelian quantum loop gases
Matthias Troyer, Simon Trebst, Kirill Shtengel +1
Two-dimensional quantum loop gases are elementary examples of topological ground states with Abelian or non-Abelian anyonic excitations. While Abelian loop gases appear as ground s…
Equilibrium free energies from non-equilibrium metadynamics
Giovanni Bussi, Alessandro Laio, Michele Parrinello
In this paper we propose a new formalism to map history-dependent metadynamics in a Markovian process. We apply this formalism to a model Langevin dynamics and determine the equili…
Collective states of interacting Fibonacci anyons
Simon Trebst, Eddy Ardonne, Adrian Feiguin +3
We show that chains of interacting Fibonacci anyons can support a wide variety of collective ground states ranging from extended critical, gapless phases to gapped phases with grou…
Optimized Broad-Histogram Ensembles for the Simulation of Quantum Systems
Stefan Wessel, Norbert Stoop, Emanuel Gull +2
The efficiency of statistical sampling in broad-histogram Monte Carlo simulations can be considerably improved by optimizing the simulated extended ensemble for fastest equilibrati…
Critical Behavior of a Trapped Interacting Bose Gas
Tobias Donner, Stephan Ritter, Thomas Bourdel +3
The phase transition of Bose-Einstein condensation is studied in the critical regime, when fluctuations extend far beyond the length scale of thermal de Broglie waves. Using matter…
Breakdown of a topological phase: Quantum phase transition in a loop gas model with tension
Simon Trebst, Philipp Werner, Matthias Troyer +2
We study the stability of topological order against local perturbations by considering the effect of a magnetic field on a spin model -- the toric code -- which is in a topological…
Ensemble Optimization Techniques for the Simulation of Slowly Equilibrating Systems
S. Trebst, D. A. Huse, E. Gull +3
Competing phases or interactions in complex many-particle systems can result in free energy barriers that strongly suppress thermal equilibration. Here we discuss how extended ense…
Bottleneck-induced transitions in a minimal model for intracellular transport
P. Pierobon, M. Mobilia, R. Kouyos +1
We consider the influence of disorder on the non-equilibrium steady state of a minimal model for intracellular transport. In this model particles move unidirectionally according to…
From Intracellular Traffic to a Novel Class of Driven Lattice Gas Models
Hauke Hinsch, Roger Kouyos, Erwin Frey
Motor proteins are key players in intracellular transport processes and biological motion. Theoretical modeling of these systems has been achieved by the use of step processes on o…
Optimized ensemble Monte Carlo simulations of dense Lennard-Jones fluids
Simon Trebst, Emanuel Gull, Matthias Troyer
We apply the recently developed adaptive ensemble optimization technique to simulate dense Lennard-Jones fluids and a particle-solvent model by broad-histogram Monte Carlo techniqu…
A Proof of Luttinger Theorem
A. Praz, J. Feldman, H. Knoerrer +1
A rigorous and simple perturbative proof of Luttinger's theorem is sketched for Fermi liquids in two and three dimensions. It is proved that in the finite volume, the quasi-particl…
Overcoming the critical slowing down of flat-histogram Monte Carlo simulations: Cluster updates and optimized broad-histogram ensembles
Yong Wu, Mathias Koerner, Louis Colonna-Romano +4
We study the performance of Monte Carlo simulations that sample a broad histogram in energy by determining the mean first-passage time to span the entire energy space of d-dimensio…
Dynamics of the Wang-Landau algorithm and complexity of rare events for the three-dimensional bimodal Ising spin glass
S. Alder, S. Trebst, A. K. Hartmann +1
We investigate the performance of flat-histogram methods based on a multicanonical ensemble and the Wang-Landau algorithm for the three-dimensional +/- J spin glass by measuring ro…
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…
Performance Limitations of Flat Histogram Methods and Optimality of Wang-Landau Sampling
P. Dayal, S. Trebst, S. Wessel +4
We determine the optimal scaling of local-update flat-histogram methods with system size by using a perfect flat-histogram scheme based on the exact density of states of 2D Ising m…
