We derive exact analytic expressions for the n-body local correlations in the one- dimensional Bose gas with contact repulsive interactions (Lieb-Liniger model) in the …
We present a comprehensive review on the state-of-the-art of the approximate analytic approaches describing the finite-temperature thermodynamic quantities of the Lieb-Liniger …

We derive exact formulas for the expectation value of local observables in a one- dimensional gas of bosons with point-wise repulsive interactions (Lieb–Liniger model) …
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 …

We consider the XY spin chain with arbitrary time-dependent magnetic field and anisotropy. We argue that a certain subclass of Gaussian states, called Coherent Ensemble (CE) …
We provide a thorough characterisation of the zero-temperature one-particle density matrix of trapped interacting anyonic gases in one dimension, exploiting recent advances in the …

We derive the low-temperature large-distance asymptotics of the transversal two-point functions of the XXZ chain by summing up the asymptotically dominant terms of their …
A quantum system exhibits off-diagonal long-range order (ODLRO) when the largest eigenvalue $\lambda_0 $ of the one-body-density matrix scales as $\lambda_0\sim N …
We address the problem of calculating the correlation functions of one-dimensional two- component gases with strong repulsive contact interactions. The model considered in this …
