Περίληψη:
In this brief, the spontaneous symmetry breaking (SSB) of the phi(4)
theory in phase space, is studied. This phase space results from the
appropriate system of Poincare maps, produced in both the Minkowski and
the Euclidean time. The importance of discretization in the creation of
phase space, is highlighted. A series of interesting, novel, unknown
behaviors are reported for the first time; among them the most
characteristic is the change in stability. In specific, the stable fixed
points of the phi(4) potential appear as unstable ones, in phase space.
Additionally, in the Euclidean-time phase space a unique instability in
the position of the critical point, can be created. This instability is
further proposed to host tachyonic field in Euclidean space.
