Query: Investigation of the 1+1 dimensional Thirring model using the method of
  matrix product states   We present preliminary results of a study on the non-thermal phase structure
of the (1+1) dimensional massive Thirring model, employing the method of matrix
product states. Through investigating the entanglement entropy, the fermion
correlators and the chiral condensate, it is found that this approach enables
us to observe numerical evidence of a Kosterlitz-Thouless phase transition in
the model.
