"Matrix Product States for Relativistic Quantum Gauge Field Theories"

Abstract:
In this talk I will describe our work on the simulation of the Schwinger 
model
(i.e. d=1+1 QED) with matrix product states (MPS). I will discuss some 
systematic
aspects of our approach like the truncation of the local infinite 
bosonic gauge field
Hilbert space, or the incorporation of local gauge invariance into the 
MPS anzats.
Furthermore, I will go through some of our results: the simulation of 
the particle
excitations ('mesons' of confined electron/positron pairs), of string 
breaking for
heavy probe charges and last but not least of the real-time evolution 
that occurs
from a background electric field quench (i.e. the full quantum Schwinger 
effect).
