A Stable, Recursive Auxiliary Field Quantum Monte Carlo Algorithm in the Canonical Ensemble: Applications to Thermometry and the Hubbard Model
Tong Shen, Hatem Barghathi, Jiangyong Yu +2
Many experimentally-accessible, finite-sized interacting quantum systems are most appropriately described by the canonical ensemble of statistical mechanics. Conventional numerical…
Strain-induced superfluid transition for atoms on graphene
Sang Wook Kim, Mohamed Elsayed, Nathan S. Nichols +5
Bosonic atoms deposited on atomically thin substrates represent a playground for exotic quantum many-body physics due to the highly-tunable, atomic-scale nature of the interaction…
Robust charge-density wave correlations in the electron-doped single-band Hubbard model
Peizhi Mai, Nathan S. Nichols, Seher Karakuzu +4
There is growing evidence that the hole-doped single-band Hubbard and - models do not have a superconducting ground state reflective of the high-temperature cuprate supercond…
Spin Squeezing as a Probe of Emergent Quantum Orders
Ilija K. Nikolov, Stephen Carr, Adrian G. Del Maestro +2
Nuclear magnetic resonance (NMR) experiments can reveal local properties in materials, but are often limited by the low signal-to-noise ratio. Spin squeezed states have an improved…
Multi-modal spectroscopy of order parameter distributions
Stephen Carr, Ilija K. Nikolov, Rong Cong +3
We present a multi-modal spectroscopic paradigm that enables independent measurement of charge and spin degrees of freedom (DOF) in strongly correlated materials. This spin-based t…
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…
Experimental Realization of One Dimensional Helium
Adrian Del Maestro, Nathan S. Nichols, Timothy R. Prisk +2
The realization of experimental platforms exhibiting one dimensional (1D) quantum phenomena has been elusive, due to their inherent lack of stability, with a few notable exceptions…
A Group-Equivariant Autoencoder for Identifying Spontaneously Broken Symmetries
Devanshu Agrawal, Adrian Del Maestro, Steven Johnston +1
We introduce the group-equivariant autoencoder (GE-autoencoder) -- a deep neural network (DNN) method that locates phase boundaries by determining which symmetries of the Hamiltoni…
A Parameter-Free Differential Evolution Algorithm for the Analytic Continuation of Imaginary Time Correlation Functions
Nathan S. Nichols, Paul Sokol, Adrian Del Maestro
We report on Differential Evolution for Analytic Continuation (DEAC): a parameter-free evolutionary algorithm to generate the dynamic structure factor from imaginary time correlati…
