Parallel time-dependent variational principle algorithm for matrix product states
Paul Secular, Nikita Gourianov, Michael Lubasch +3
Combining the time-dependent variational principle (TDVP) algorithm with the parallelization scheme introduced by Stoudenmire and White for the density matrix renormalization group…
Benchmarking Semiclassical and Perturbative Methods for Real-time Simulations of Cavity-Bound Emission and Interference
Norah M. Hoffmann, Christian Schäfer, Niko Säkkinen +3
We benchmark a selection of semiclassical and perturbative dynamics techniques by investigating the correlated evolution of a cavity-bound atomic system to assess their applicabili…
Pulse and continuously driven many-body quantum dynamics of bosonic impurities in a Bose-Einstein condensate
K. Mukherjee, S. I. Mistakidis, S. Majumder +1
We unravel the periodically driven dynamics of two repulsively interacting bosonic impurities within a bosonic bath upon considering either the impact of a finite pulse or a contin…
Emergent limit cycles and time crystal dynamics in an atom-cavity system
Hans Keßler, Jayson G. Cosme, Michal Hemmerling +2
We propose an experimental realization of a time crystal using an atomic Bose-Einstein condensate in a high finesse optical cavity pumped with laser light detuned to the blue side…
NetKet: A Machine Learning Toolkit for Many-Body Quantum Systems
Giuseppe Carleo, Kenny Choo, Damian Hofmann +15
We introduce NetKet, a comprehensive open source framework for the study of many-body quantum systems using machine learning techniques. The framework is built around a general and…
Capturing Vacuum Fluctuations and Photon Correlations in Cavity Quantum Electrodynamics with Multi-Trajectory Ehrenfest Dynamics
Norah M. Hoffmann, Christian Schäfer, Angel Rubio +2
We describe vacuum fluctuations and photon-field correlations in interacting quantum mechanical light-matter systems, by generalizing the application of mixed quantum-classical dyn…
