Thermodynamics and magnetism in the two-dimensional to three-dimensional crossover of the Hubbard model

E Ibarra-García-Padilla, R Mukherjee, RG Hulet… - Physical Review A, 2020 - APS
The realization of antiferromagnetic (AF) correlations in ultracold fermionic atoms on an
optical lattice is a significant achievement. Experiments have been carried out in one, two …

Obstructed atomic insulators and superfluids of fermions coupled to gauge fields

BP Parasar, VB Shenoy - Physical Review B, 2023 - APS
Studying spin-1 2 fermions coupled to Z 2 gauge fields on the square lattice, we show how a
spatial modulation of the fermion hopping amplitude allows for the realization of various …

Finite-temperature study of correlations in a bilayer band insulator

Y Prasad - Physical Review B, 2022 - APS
We perform the finite-temperature determinant quantum Monte Carlo simulation for the
attractive Hubbard model on the half-filled bilayer square lattice. Recent progress on optical …

Obstructed Atomic Insulators and Superfluids of Fermions Coupled to Gauge Fields

BP Parasar, VB Shenoy - arXiv preprint arXiv:2212.14625, 2022 - arxiv.org
We study spin-$\frac {1}{2} $ fermions coupled to $\mathbb {Z} _2 $ gauge fields on a lattice.
We show how a spatial modulation of the fermion hopping allows for the realization of …

Cooling quantum gases with entropy localization

FN Ünal, EJ Mueller - New Journal of Physics, 2017 - iopscience.iop.org
We study the dynamics of entropy in a time dependent potential and explore how disorder
influences this entropy flow. We show that disorder can trap entropy at the edge of the …
