We consider some extensions of the relation which has been obtained by Nambu and Luri\'e between an elastic process and the accompanying soft pion emission process under the assumption of approximate ${\ensuremath{\gamma}}_{5}$ invariance. In particu

In this paper we show that a coherent‐state path‐integral treatment significantly simplifies the analysis of the Lee model, including higher sector calculations. The method may be applicable to more general field theories. However, the special pr

The statistical mechanics of snoidal kinks in a ${\ensuremath{\varphi}}^{4}$ field system in one space and one time dimension has been extended to include lowest-order interaction effects. These effects remove the phase transition suggested by our ea

The statistical mechanics of renormalized snoidal sine-Gordon kinks is applied to the specific heat in (CH/sub 3/)/sub 4/NMnCl/sub 3/ (TMMC) and CsNiF/sub 3/ in external magnetic fields.

A field-theoretical derivation of the vacuum-tunneling effect is presented which gives results similar to the recent work of Callan and Coleman. An expression for the decay rate is exhibited which takes into account the zero and negative eigenmodes o

We present a formulation of quantum field theory as a path-integral representation for elements of the U or S matrix in the coherent- state basis. These matrix elements are shown to serve as generating functionals for all the usual S-matrix elements
