Light-cone and diffusive propagation of correlations in a many-body dissipative system

Jean-Sebastien Bernier, Ryan Tan, Lars Bonnes +3

We analyze the propagation of correlations after a sudden interaction change in a strongly interacting quantum system in contact with an environment. In particular, we consider an…

Superoperators vs. Trajectories for Matrix Product State Simulations of Open Quantum System: A Case Study

Lars Bonnes, Andreas M. Läuchli

Quantum trajectories and superoperator algorithms implemented within the matrix product state (MPS) framework are powerful tools to simulate the real-time dynamics of open dissipat…

Probing Entanglement in Adiabatic Quantum Optimization with Trapped Ions

Philipp Hauke, Lars Bonnes, Markus Heyl +1

Adiabatic quantum optimization has been proposed as a route to solve NP-complete problems, with a possible quantum speedup compared to classical algorithms. However, the precise ro…

Dynamical and Steady State Properties of a Bose-Hubbard Chain with Bond-Dissipation: A Study based on Matrix Product Operators

Lars Bonnes, Daniel Charrier, Andreas M. Läuchli

We study a dissipative Bose-Hubbard chain subject to an engineered bath using a superoperator approach based on matrix product operators. The dissipation is engineered to stabilize…

"Light-cone" dynamics after quantum quenches in spin chains

Lars Bonnes, Fabian H. L. Essler, Andreas M. Läuchli

Signal propagation in the non equilibirum evolution after quantum quenches has recently attracted much experimental and theoretical interest. A key question arising in this context…

Entanglement negativity via replica trick: a Quantum Monte Carlo approach

Chia-Min Chung, Vincenzo Alba, Lars Bonnes +2

Motivated by recent developments in conformal field theory (CFT), we devise a Quantum Monte Carlo (QMC) method to calculate the moments of the partially transposed reduced density…
