Superfluidity in the spin-1/2 XY model with power-law interactions
Muhammad Shaeer Moeed, Costanza Pennaforti, Adrian Del Maestro +1
In trapped-ion quantum simulators, effective spin-1/2 XY interactions can be engineered via laser-induced coupling between internal atomic states and collective phonon modes. In th…
A Scaling Function for the Particle Entanglement Entropy of Fermions
Harini Radhakrishnan, Matthias Thamm, Hatem Barghathi +2
Entanglement entropy under a particle bipartition provides complementary information to mode entanglement as it is sensitive to interactions and particle statistics at leading orde…
Quantum Atomic Matter Near Two-Dimensional Materials in Microgravity
Adrian Del Maestro, Sang Wook Kim, Nicholas P. Bigelow +2
Novel two-dimensional (2D) atomically flat materials, such as graphene and transition-metal dichalcogenides, exhibit unconventional Dirac electronic spectra. We propose to effectiv…
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…
One-particle entanglement for one dimensional spinless fermions after an interaction quantum quench
Matthias Thamm, Harini Radhakrishnan, Hatem Barghathi +2
Particle entanglement provides information on quantum correlations in systems of indistinguishable particles. Here, we study the one particle entanglement entropy for an integrable…
Balls and Walls: A Compact Unary Coding for Bosonic States
Hatem Barghathi, Caleb Usadi, Micah Beck +1
We introduce a unary coding of bosonic occupation states based on the famous "balls and walls" counting for the number of configurations of indistinguishable particles on d…
Particle partition entanglement of one dimensional spinless fermions
Hatem Barghathi, Emanuel Casiano-Diaz, Adrian Del Maestro
We investigate the scaling of the Rényi entanglement entropies for a particle bipartition of interacting spinless fermions in one spatial dimension. In the Tomonaga-Luttinger liqui…
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…
