Phase structure and real-time dynamics of the massive Thirring model in 1+1 dimensions using the tensor-network method
January 03, 2020
We present concluding results from our study for
zero-temperature phase structure
of the massive Thirring model in 1+1 dimensions with staggered
regularisation. Employing the method of matrix product states, several
quantities, including two types of correlators, are investigated, leading to numerical evidence of a Berezinskii-Kosterlitz-Thouless phase transition. Exploratory results for real-time dynamics pertaining to this transition, obtained
using the approaches of variational uniform matrix product state and time-dependent
variational principle, are also discussed.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
