Non-equilibrium dynamics of interacting many-body quantum systems in one dimension

Abstract:

In this thesis we study three examples of interacting many-body systems undergoing a non equilibrium time evolution.

Firstly we consider the time evolution in an integrable system: the sine-Gordon field theory in the repulsive regime. We will focus on the one point function of the semi-local vertex operator eiβφ(x)/2 on a specific class of initial states. By analytical means we show that the expectation value considered decays exponentially to ze...
