Higher order local and non local correlations for 1D strongly interacting Bose gas

Higher order local and non local correlations for 1D strongly interacting Bose gas - The correlation function is an important quantity in the physics of ultracold quantum gases because it provides information about the quantum many-body wave function beyond the simple density profile. In this paper we first study the M-body local correlation functions, g M , of the one-dimensional (1D) strongly repulsive Bose gas within the Lieb–Liniger model using the analytical method
