The existence and interaction problem of lambda phi 4 in a four-dimensional homogeneous and isotropic spacetime is studied. The approach is based on a variational technique. In the paper, and only for reasons of technical and conc

Some new exact path integral treatments are presented. These are the path integrals for the symmetric top, the 'smooth step', the Rosen-Morse- and the Manning-Rosen-potential. By appropriate spacetime transformations these path in

In the broken phase of the four-dimensional Ising model tunneling between the two degenerate minima of the effective potential takes place in a finite volume. We study this phenomenon numerically. The energies of the lowest zero mo
