Quantum dynamics in interacting Bose gases.

Determining dynamical properties of the Lieb-Liniger model of interacting bosons is notoriously difficult, both in equilibrium at finite temperatures and out of equilibrium. I discuss recent progress in determining dynamical properties, both in and out of equilibrium, in the regime of strong interactions. This is based on two approaches: (i) combining integrability methods with an expansion in the inverse interactions strength; and (ii) on an explicit construction of the fermionic dual of the Lieb-Liniger model, in which fermion-fermion interactions can be treated perturbatively in the strong coupling regime.
