Entanglement properties of the antiferromagnetic-singlet transition in the Hubbard model on bilayer square lattices

Chia-Chen Chang, Rajiv R. P. Singh, Richard T. Scalettar

We calculate the bipartite \Renyi entanglement entropy of an $L\times L\times 2$ bilayer Hubbard model using a determinantal quantum Monte Carlo method recently proposed by Grover…
