Entanglement production in the dynamical Casimir effect at parametric resonance
Ivan Romualdo, Lucas Hackl, Nelson Yokomizo
The particles produced from the vacuum in the dynamical Casimir effect are highly entangled. In order to quantify the correlations generated by the process of vacuum decay induced…

Gaussian time dependent variational principle for the Bose-Hubbard model
Tommaso Guaita, Lucas Hackl, Tao Shi +3
We systematically extend Bogoliubov theory beyond the mean field approximation of the Bose-Hubbard model in the superfluid phase. Our approach is based on the time dependent variat…

Minimal energy cost of entanglement extraction
Lucas Hackl, Robert H. Jonsson
We compute the minimal energy cost for extracting entanglement from the ground state of a bosonic or fermionic quadratic system. Specifically, we find the minimal energy increase $…
