Description
Above the Curie temperature, the Ising model partition function can
vanish under the effect of an imaginary magnetic field, as first
shown by Lee and Yang. This system has a severe sign problem.
We study it numerically, using the density of states method.
In particular, we consider how the computer effort scales with
the system size.
