abstract = {Tensor network (TN) methods, in particular the Matrix
Product States (MPS) ansatz, have proven to be a useful tool
in analyzing the properties of lattice gauge theories. They
allow for a very good precision, much better than standard
Monte Carlo (MC) techniques for the models that have been
studied so far, due to the possibility of reaching much
smaller lattice spacings. The real reason for the interest
in the TN approach, however, is its ability, shown so far in
several condensed matter models, to deal with theories which
exhibit the notorious sign problem in MC simulations. This
makes it prospective for dealing with the non-zero chemical
potential in QCD and other lattice gauge theories, as well
as with real-time simulations. In this paper, using matrix
product operators, we extend our analysis of the Schwinger
model at zero temperature to show the feasibility of this
approach also at finite temperature. This is an important
step on the way to deal with the sign problem of QCD. We
analyze in detail the chiral symmetry breaking in the
massless and massive cases and show that the method works
very well and gives good control over a broad range of
temperatures, essentially from zero to infinite
temperature.},
