Collective quantum fields

Collective quantum fields It is the purpose of this book to discuss a simple technique via Feynman pathintegral formulas in which the transformation to collective elds amounts to merechanges of integration variables in functional integrals. After the transformation,the path formulation will again be discarded. The resulting eld theory is quantizedin the standard fashion and the fundamental quanta directly describe the collectiveexcitations
