Entanglement entropy in low-energy field theories at finite chemical potential
Ivan Morera, Irénée Frérot, Artur Polls +1
We investigate the leading area-law contribution to entanglement entropy in a system described by a general Lagrangian with O(2) symmetry containing first- and second-order time de…

Entanglement structure of a quantum simulator: the two-component Bose-Hubbard model
Ivan Morera, Artur Polls, Bruno Juliá-Díaz
We consider a quantum simulator of the Heisenberg chain with ferromagnetic interactions based on the two-component 1D Bose-Hubbard model at filling equal to two in the strong coupl…
