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…
Rényi generalization of the operational entanglement entropy
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…
Spatial entanglement entropy in the ground state of the Lieb-Liniger model
C. M. Herdman, P. -N. Roy, R. G. Melko +1
We consider the entanglement between two spatial subregions in the Lieb-Liniger model of bosons in one spatial dimension interacting via a contact interaction. Using ground state p…
Entangling qubit registers via many-body states of ultracold atoms
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…
Particle partition entanglement of bosonic Luttinger liquids
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…
A path integral Monte Carlo method for Rényi entanglement entropies
C. M. Herdman, Stephen Inglis, P. -N. Roy +2
We introduce a quantum Monte Carlo algorithm to measure the Rényi entanglement entropies in systems of interacting bosons in the continuum. This approach is based on a path integra…
Particle entanglement in continuum many-body systems via quantum Monte Carlo
C. M. Herdman, P. -N. Roy, R. G. Melko +1
Entanglement of spatial bipartitions, used to explore lattice models in condensed matter physics, may be insufficient to fully describe itinerant quantum many-body systems in the c…
