Density form factors of the 1D Bose gas for finite entropy states
Jacopo De Nardis, Miłosz Panfil
We consider the Lieb-Liniger model for a gas of bosonic interacting particles. Using Algebraic Bethe Ansatz results we compute the thermodynamic limit of the form factors of th…

Analytical expression for a post-quench time evolution of the one-body density matrix of one-dimensional hard-core bosons
Jacopo De Nardis, Jean-Sébastien Caux
We apply the logic of the quench action to give an exact analytical expression for the time evolution of the one-body density matrix after an interaction quench in the Lieb-Liniger…
