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…
