Correlation properties of a one-dimensional repulsive Bose gas at finite temperature
We present a comprehensive study shedding light on how thermal fluctuations affect correlations in a Bose gas with contact repulsive interactions in one spatial dimension. The pair correlation function, the static structure factor, and the one-body density ...
IOP Publishing Ltd2023Optomechanical response of a strongly interacting Fermi gas
Jean-Philippe Brantut, Timo Zwettler, Victor Youri Helson, Kevin Etienne Robert Roux, Hideki Konishi
We study a Fermi gas with strong, tunable interactions dispersively coupled to a high-finesse cavity. Upon probing the system along the cavity axis, we observe a strong optomechanical Kerr nonlinearity originating from the density response of the gas to th ...
AMER PHYSICAL SOC2022Hole-induced anomaly in the thermodynamic behavior of a one-dimensional Bose gas
We reveal an intriguing anomaly in the temperature dependence of the specific heat of a one-dimensional Bose gas. The observed peak holds for arbitrary interaction and remembers a superfluid-to-normal phase transition in higher dimensions, but phase transi ...
SCIPOST FOUNDATION2022Artificial out-of-plane Ising antiferromagnet on the kagome lattice with very small farther-neighbor couplings
Frédéric Mila, Jeanne Colbois, Xueqiao Wang
Despite their simple formulation, short-range classical antiferromagnetic Ising models on frustrated lattices give rise to exotic phases of matter, in particular, due to their macroscopic ground-state degeneracy. Recent experiments on artificial spin syste ...
