Dynamical behavior of spatially inhomogeneous relativistic $\lambda {\varphi }^4$ quantum field theory in the Hartree approximation

Luis M. A. Bettencourt, Karen Pao, J. G. Sanderson

We study the dynamics of a spatially inhomogeneous quantum $\lambda {\varphi }^4$ field theory in 1+1 dimensions in the Hartree approximation. In particular, we investigate the long-time behavior…
