Universal behavior beyond multifractality in quantum many-body systems
David J. Luitz, Fabien Alet, Nicolas Laflorencie
How many states of a configuration space contribute to a wave-function? Attempts to answer this ubiquitous question have a long history in physics and chemistry, and are keys to un…
Geometric entanglement of critical XXZ and Ising chains and Affleck-Ludwig boundary entropies
Jean-Marie Stéphan, Grégoire Misguich, Fabien Alet
We study the geometrical entanglement of the XXZ chain in its critical regime. Recent numerical simulations [Q.-Q. Shi, R. Orús, J. O. Fjærestad and H.-Q Zhou, New J. Phys. {\bf 12…
Coulomb gas transitions in three-dimensional classical dimer models
Gang Chen, Jan Gukelberger, Simon Trebst +2
Close-packed, classical dimer models on three-dimensional, bipartite lattices harbor a Coulomb phase with power-law correlations at infinite temperature. Here, we discuss the natur…
The semiflexible fully-packed loop model and interacting rhombus tilings
Jesper Lykke Jacobsen, Fabien Alet
Motivated by a recent adsorption experiment [M.O. Blunt et al., Science 322, 1077 (2008)], we study tilings of the plane with three different types of rhombi. An interaction disfav…
Correlations and order parameter at a Coulomb-crystal phase transition in a three-dimensional dimer model
Gregoire Misguich, Vincent Pasquier, Fabien Alet
The three-dimensional classical dimer model with interactions shows an unexpected continuous phase transition between an ordered dimer crystal and a Coulomb liquid. A detailed anal…
Criticality of a classical dimer model on the triangular lattice
F. Trousselet, P. Pujol, F. Alet +1
We consider a classical interacting dimer model which interpolates between the square lattice case and the triangular lattice case by tuning a chemical potential in the diagonal bo…
Classical dimers with aligning interactions on the square lattice
Fabien Alet, Yacine Ikhlef, Jesper Lykke Jacobsen +2
We present a detailed study of a model of close-packed dimers on the square lattice with an interaction between nearest-neighbor dimers. The interaction favors parallel alignment o…
Unconventional continuous phase transition in a three dimensional dimer model
Fabien Alet, Gregoire Misguich, Vincent Pasquier +2
Phase transitions occupy a central role in physics, due both to their experimental ubiquity and their fundamental conceptual importance. The explanation of universality at phase tr…
Interacting classical dimers on the square lattice
Fabien Alet, Jesper Lykke Jacobsen, Gregoire Misguich +3
We study a model of close-packed dimers on the square lattice with a nearest neighbor interaction between parallel dimers. This model corresponds to the classical limit of quantum…
Bosons in optical lattices - from the Mott transition to the Tonks-Girardeau gas
S. Wessel, F. Alet, S. Trebst +3
We present results from quantum Monte Carlo simulations of trapped bosons in optical lattices, focusing on the crossover from a gas of softcore bosons to a Tonks-Girardeau gas in a…
Local Simulation Algorithms for Coulombic Interactions
L. Levrel, F. Alet, J. Rottler +1
We consider dynamically constrained Monte-Carlo dynamics and show that this leads to the generation of long ranged effective interactions. This allows us to construct a local algor…
Quantum Monte Carlo simulations of confined bosonic atoms in optical lattices
Stefan Wessel, Fabien Alet, Matthias Troyer +1
We study properties of ultra-cold bosonic atoms in one, two and three dimensional optical lattices by large scale quantum Monte Carlo simulations of the Bose Hubbard model in parab…
Dual Geometric Worm Algorithm for Two-Dimensional Discrete Classical Lattice Models
Peter Hitchcock, Erik S. Sørensen, Fabien Alet
We present a dual geometrical worm algorithm for two-dimensional Ising models. The existence of such dual algorithms was first pointed out by Prokof'ev and Svistunov \cite{Prokofev…
Wang-Landau sampling for quantum systems: algorithms to overcome tunneling problems and calculate the free energy
Matthias Troyer, Stefan Wessel, Fabien Alet
We present a generalization of the classical Wang-Landau algorithm [Phys. Rev. Lett. 86, 2050 (2001)] to quantum systems. The algorithm proceeds by stochastically evaluating the co…
Local Simulation Algorithms for Coulomb Interaction
A. C. Maggs, V. Rossetto
Long ranged electrostatic interactions are time consuming to calculate in molecular dynamics and Monte-Carlo simulations. We introduce an algorithmic framework for simulating charg…
