Scattering by harmonically trapped 2D quantum gas near and around the critical regime

Abstract

In this article, we analytically explore the quantum phenomena of scattering by harmonically trapped 2D quantum gases. We show the temperature’s dependence on the differential scattering cross-section (DSC) near and around the critical transition regime for both particle and light scattering cases separately. For the particle scattering case, we consider scatterers with quantized bound motion in a harmonic trap. Our findings on the structure factor for light scattering give phase transition phenomena for 2D bosonic atoms and the thermal behavior of the system. This result has practical significance for recent experimental setups such as in-situ image analysis and bosonic
simulations. Finally, we show the temperature-dependent refractive index for a 2D harmonically trapped bosonic medium. This parameter is important in neutron scattering experiments.

Superfluid Mott-insulator quantum phase transition in an open cavity optomagnonic system

“…Quantum simulation provides a useful tool to explore new phenomena in quantum strongly correlated systems [1][2][3][4][5], exciton-polariton condensates [6][7][8], and high-temperature superconductivity [9][10][11]. Due to the controllability and compatility of atomic and optical systems, coupled cavity array is an promising and widely accepted system for quantum simulations.…”
