Cluster Gutzwiller Monte Carlo approach for a critical dissipative spin model
Dolf Huybrechts, Michiel Wouters
We study the influence of short-range quantum correlations and classical spatial correlations on the phase diagram of the dissipative XYZ model by using a Gutzwiller Monte carlo me…
Gaussian Quantum Trajectories for the Variational Simulation of Open Quantum-Optical Systems
Wouter Verstraelen, Michiel Wouters
We construct a class of variational methods for the study of open quantum systems based on Gaussian ansatzes for the quantum trajectory formalism. Gaussianity in the conjugate posi…
Prethermalization to thermalization crossover in a dilute Bose gas following an interaction ramp
Mathias Van Regemortel, Hadrien Kurkjian, Iacopo Carusotto +1
The dynamics of a weakly interacting Bose gas at low temperatures is close to integrable due to the approximate quadratic nature of the many-body Hamiltonian. While the short-time…
