TensorMixedStates: a Julia library for simulating pure and mixed quantum states using matrix product states
Jérôme Houdayer, Grégoire Misguich
We introduce TensorMixedStates, a Julia library built on top of ITensor which allows the simulation of quantum systems in the presence of dissipation using matrix product states (M…
A solvable model for graph state decoherence dynamics
Jérôme Houdayer, Haggai Landa, Grégoire Misguich
We present an exactly solvable toy model for the continuous dissipative dynamics of permutation-invariant graph states of qubits. Such states are locally equivalent to an -q…
Low-temperature behavior of two-dimensional Gaussian Ising spin glasses
J. Houdayer, Alexander K. Hartmann
We perform Monte Carlo simulations of large two-dimensional Gaussian Ising spin glasses down to very low temperatures . Equilibration is ensured by using a cluster algori…
Deviations from the mean field predictions for the phase behaviour of random copolymers melts
J. Houdayer, M. Mueller
We investigate the phase behaviour of random copolymers melts via large scale Monte Carlo simulations. We observe macrophase separation into A and B--rich phases as predicted by me…
The wormhole move: A new algorithm for polymer simulations
J. Houdayer
A new Monte Carlo move for polymer simulations is presented. The ``wormhole'' move is build out of reptation steps and allows a polymer to reptate through a hole in space; it is ab…
Zero-temperature responses of a 3D spin glass in a field
F. Krzakala, J. Houdayer, E. Marinari +2
We probe the energy landscape of the 3D Edwards-Anderson spin glass in a magnetic field to test for a spin glass ordering. We find that the spin glass susceptibility is anomalously…
A hierarchical approach for computing spin glass ground states
Jerome Houdayer, Olivier C. Martin
We describe a numerical algorithm for computing spin glass ground states with a high level of reliability. The method uses a population based search and applies optimization on mul…
Large-scale low-energy excitations in 3-d spin glasses
J. Houdayer, F. Krzakala, O. C. Martin
We numerically extract large-scale excitations above the ground state in the 3-dimensional Edwards-Anderson spin glass with Gaussian couplings. We find that associated energies are…
Reply to Comment on "Ising Spin Glasses in a Magnetic Field"
J. Houdayer, O. C. Martin
The problem of the survival of a spin glass phase in the presence of a field has been a challenging one for a long time. To date, all attempts using equilibrium Monte Carlo methods…
A geometrical picture for finite dimensional spin glasses
J. Houdayer, O. C. Martin
A controversial issue in spin glass theory is whether mean field correctly describes 3-dimensional spin glasses. If it does, how can replica symmetry breaking arise in terms of spi…
Renormalization for Discrete Optimization
J. Houdayer, O. C. Martin
The renormalization group has proven to be a very powerful tool in physics for treating systems with many length scales. Here we show how it can be adapted to provide a new class o…
Ising Spin Glasses in a Magnetic Field
J. Houdayer, O. C. Martin
Ground states of the three dimensional Edwards-Anderson spin glass are computed in the presence of an external magnetic field. Our algorithm is sufficiently powerful for us to trea…
Droplet Phenomenology and Mean Field in a Frustrated and Disordered System
J. Houdayer, O. C. Martin
The low lying excited states of the three-dimensional minimum matching problem are studied numerically. The excitations' energies grow with their size and confirm the droplet pictu…
Comparing Mean Field and Euclidean Matching Problems
J. Houdayer, J. H. Boutet de Monvel, O. C. Martin
Combinatorial optimization is a fertile testing ground for statistical physics methods developed in the context of disordered systems, allowing one to confront theoretical mean fie…
