Quantum properties of light scattered from structured many-body phases of ultracold atoms in quantum optical lattices

TL;DR

This paper explores how quantum many-body phases of ultracold atoms in optical lattices influence the quantum properties of scattered light, revealing tunable nonclassical features arising from atom-light interactions.

Contribution

It demonstrates how the interplay between long-range cavity-mediated interactions and short-range atomic processes can be used to design and optimize nonclassical light properties in structured quantum phases.

Findings

Light exhibits nonclassical features influenced by atomic phases

Quantum properties of light can be tuned via atom-light interactions

Structured many-body phases modify scattering properties

Abstract

Quantum trapping potentials for ultracold gases change the landscape of classical properties of scattered light and matter. The atoms in a quantum many-body correlated phase of matter change the properties of light and vice versa. The properties of both light and matter can be tuned by design and depend on the interplay between long-range (nonlocal) interactions mediated by an optical cavity and short-range processes of the atoms. Moreover, the quantum properties of light get significantly altered by this interplay, leading the light to have nonclassical features. Further, these nonclassical features can be designed and optimised.
