Temperature-induced interaction: (lambda)(phi)4 theory

We study the possibility that a field theory is interacting and bounded only above a certain temperature, while not existing below it. Within the Gaussian variational approximation used we find a phase for λ φ 4 in four dimensions in which this phenomenon occurs.
