Non-equilibrium dynamics - from hydrodynamics to tensor networks

Abstract:
In heavy-ion collisions, the high energies involved dissolves the hadrons into the constituent quarks and gluons, which form a new state of matter: the quark-gluon plasma. Efforts to describe the dynamics and formation of the plasma has motivated research into non-equilibrium dynamics and thermalization and has raised foundational questions about the applicability of hydrodynamics.

Motivated by this, we investigated how we can use tensor networks to simulate interacting quantum field theories and get some insight into the dynamics and thermalization. I'll also describe my more recent work where these methods are used to investigate Majorana fermions in topological phases.
