Entanglement entropy of two-species hard-core bosons in one dimension
We study the bipartite entanglement entropy of a model for two-species hard-core bosons in one dimension. In this model, the same-species bosons satisfy hard-core conditions while the different-species bosons are allowed to occupy the same site with a local interaction strength U . We measure the bi...

. We measure the bipartite entanglement entropy of the ground states of an infinite-size system as a function of
U
in the half-filled and the off-half-filled cases. To achieve this goal, we use a time-evolution-block-decimation method with large bond dimensions up to 300. |
