A Path Integral Ground State Monte Carlo Algorithm for Entanglement of Lattice Bosons
Emanuel Casiano-Diaz, C. M. Herdman, Adrian Del Maestro
A ground state path integral quantum Monte Carlo algorithm is introduced that allows for the study of entanglement in lattice bosons at zero temperature. The Rényi entanglement ent…
Generating accessible entanglement in bosons via pair-correlated tunneling
T. J. Volkoff, C. M. Herdman
We consider an extended Bose-Hubbard model that includes pair-correlated tunneling. We demonstrate that a minimal four-mode implementation of this model exhibits a pair-correlated…

Hatem Barghathi, C. M. Herdman, Adrian Del Maestro
Operationally accessible entanglement in bipartite systems of indistinguishable particles could be reduced due to restrictions on the allowed local operations as a result of partic…

Owen Myers, C. M. Herdman
We introduce the quantum dimer-pentamer model (QDPM) on the square lattice. This model is a generalization of the square lattice quantum dimer model as its configuration space comp…
Entanglement area law in superfluid He
C. M. Herdman, P. -N. Roy, R. G. Melko +1
Area laws were first discovered by Bekenstein and Hawking, who found that the entropy of a black hole grows proportional to its surface area, and not its volume. Entropy area laws…

R. G. Melko, C. M. Herdman, D. Iouchtchenko +2
Inspired by the experimental measurement of the Renyi entanglement entropy in a lattice of ultracold atoms by Islam et al., [Nature 528, 77 (2015)] we propose a method to entangle…
Detecting Goldstone Modes with Entanglement Entropy
B. Kulchytskyy, C. M. Herdman, Stephen Inglis +1
In the face of mounting numerical evidence, Metlitski and Grover [arXiv:1112.5166] have given compelling analytical arguments that systems with spontaneous broken continuous symmet…

C. M. Herdman, A. Del Maestro
We consider the Rényi entanglement entropy of bosonic Luttinger liquids under a particle bipartition and demonstrate that the leading order finite-size scaling is logarithmic in th…
