Query: Dimensional crossover in ultracold Fermi gases from Functional
  Renormalisation   We investigate the dimensional crossover from three to two dimensions in an
ultracold Fermi gas across the whole BCS-BEC crossover. Of particular interest
is the strongly interacting regime as strong correlations are more pronounced
in reduced dimensions. Our results are obtained from first principles within
the framework of the functional renormalisation group (FRG). Here, the
confinement of the transverse direction is imposed by means of periodic
boundary conditions. We calculate the equation of state, the gap parameter at
zero temperature and the superfluid transition temperature across a wide range
of transversal confinement length scales. Particular emphasis is put on the
determination of the finite temperature phase diagram for different confinement
length scales. In the end, our results are compared with recent experimental
observations and we discuss them in the context of other theoretical works.
