摘要：

We show that a system of bosons in a T = 0 quantum field theory can present metastable ground states with spontaneous symmetry breaking, even in the absence of an imaginary mass term. This gives a natural explanation to the Davis-Shellard background field e(-i omega 0t) and adds a new degree of freedom in boson systems, with possible applications in cosmology, condensed matter and high energy physics.
