Query: Symmetry breaking in nonuniform noncommutative $\lambda\phi^4$ theory at
  finite temperature   We consider the 2PI Cornwall-Jackiw-Tomboulis effective action at finite
temperature for a noncommutative real scalar field theory in 4 dimensions, with
noncommutativity among space and time variables. By means of a Rayleig-Ritz
variation, we study the solutions of a stripe type nonuniform background, which
depends on space and time, and hence on temperature. The analysis in the first
approximation shows that such solutions appear in the planar limit, as already
known, but also under normal noncommutativity, in an anisotropic region which
has not been considered. Further we show that the transition from the uniform
ordered phase to the non uniform one is first order.
