Entanglement Spectroscopy using Quantum Monte Carlo
Chia-Min Chung, Lars Bonnes, Pochung Chen +1
We present a numerical scheme to reconstruct a subset of the entanglement spectrum of quantum many body systems using quantum Monte Carlo. The approach builds on the replica trick…
Quantum and Thermal Transitions Out of the Pair-Supersolid Phase of Two-Species Bosons in Lattice
Chia-Min Chung, Shiang Fang, Pochung Chen
We investigate two-species bosons in a two-dimensional square lattice by quantum Monte Carlo method. We show that the inter-species attraction and nearest-neighbor intra-species re…
Quantum Criticality from in-situ Density Imaging
Shiang Fang, Chia-Ming Chung, Ping Nang Ma +2
We perform large-scale Quantum Monte Carlo (QMC) simulations for strongly interacting bosons in a 2D optical lattice trap, and confirm an excellent agreement with the benchmarking…
