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…
Thermal phase transitions in a honeycomb lattice gas with three-body interactions
Maximilian Lohöfer, Lars Bonnes, Stefan Wessel
We study the thermal phase transitions in a classical (hard-core) lattice gas model with nearest-neighbor three-body interactions on the honeycomb lattice, based on parallel temper…
Entanglement Spectroscopy using Quantum Monte Carlo
Chia-Min Chung, Lars Bonnes, Pochung Chen +1
We present a numerical scheme to reconstruct a subset of the entanglement spectrum of quantum many body systems using quantum Monte Carlo. The approach builds on the replica trick…
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…
Thermal vs. Entanglement Entropy: A Measurement Protocol for Fermionic Atoms with a Quantum Gas Microscope
Hannes Pichler, Lars Bonnes, Andrew J. Daley +2
We show how to measure the order-two Renyi entropy of many-body states of spinful fermionic atoms in an optical lattice in equilibrium and non-equilibrium situations. The proposed…
