The fundamental goal of physics is an understanding of the forces
of nature in their simplest and most general terms. Yet there is
much more involved than just a basic set of equations which
eventually has to be solved when applied to specific problems. We
have learned in recent years that the structure of the ground state
of field theories (with which we are generally concerned) plays an
equally funda mental role as the equations of motion themselves.
Heisenberg was probably the first to recognize that the ground
state, the vacuum, could acquire certain prop erties (quantum
numbers) when he devised a theory of ferromagnetism. Since then,
many more such examples are known in solid state physics, e. g.
supercon ductivity, superfluidity, in fact all problems concerned
with phase transitions of many-body systems, which are often
summarized under the name synergetics. Inspired by the experimental
observation that also fundamental symmetries, such as parity or
chiral symmetry, may be violated in nature, it has become wide ly
accepted that the same field theory may be based on different
vacua. Practical ly all these different field phases have the
status of more or less hypothetical models, not (yet) directly
accessible to experiments. There is one magnificent ex ception and
this is the change of the ground state (vacuum) of the
electron-posi tron field in superstrong electric fields."
