Abstract: I will talk about the dynamics of the bosonic string thrown out of equilibrium by a sudden change in the compactification radius. This setup can be equivalently phrased in terms of marginal quenches of Tomonoga-Luttinger liquids via an instantaneous change in the Luttinger parameter. I will discuss some exact results for the Loschmidt echo and the evolution of the stress tensor. The dynamics turns out to be crucially dependent on the distance in moduli space measured by the Zamolodchikov metric.
