"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…
An entropy perspective on the thermal crossover in a fermionic Hubbard chain
Lars Bonnes, Hannes Pichler, Andreas M. Läuchli
We study the Renyi entropy in the finite temperature crossover regime of a Hubbard chain using quantum Monte Carlo. The ground state entropy has characteristic features such as a l…
