Luttinger Liquid of Photons and Spin-Charge Separation in Hollow-Core Fibers
Luttinger Liquid of Photons and Spin-Charge Separation in Hollow-Core Fibers
In this work we show that light-matter excitations (polaritons) generated inside a hollow-core one-dimensional fiber filled with two types of atoms, can exhibit Luttinger liquid behavior. We first explain how to prepare and drive this quantum-optical system to a strongly interacting regime, described by a bosonic two-component Lieb-Liniger model. Utilizing …
