Query: Continuous matrix product states with periodic boundary conditions and
  an application to atomtronics   We introduce a time evolution algorithm for one-dimensional quantum field
theories with periodic boundary conditions. This is done by applying the
Dirac-Frenkel time-dependent variational principle to the set of translational
invariant continuous matrix product states with periodic boundary conditions.
Moreover, the ansatz is accompanied with additional boundary degrees of freedom
to study quantum impurity problems. The algorithm allows for a cutoff in the
spectrum of the transfer matrix and thus has an efficient computational
scaling. In particular we study the prototypical example of an atomtronic
system - an interacting Bose gas rotating in a ring shaped trap in the presence
of a localised barrier potential.
