We study noncommutative field theories at finite temperature to learn more
about the degrees of freedom in the non-planar sector of these systems. We
find evidence for winding states. At temperatures for which the thermal wav
elength is smaller than the noncommutativity scale, there is a drastic redu
ction of the degrees of freedom in the non-planar sector. In this regime, t
he non-planar sector has thermodynamics resembling that of a 1 + 1 dimensio
nal field theory.
