Scalar Theories and Symmetry Breaking in the Light-Front Coupled-Cluster Method

Research output: Contribution to journalArticle

Abstract

We extend the light-front coupled-cluster (LFCC) method to include zero modes explicitly, in order to be able to compute vacuum structure in theories with symmetry breaking. Applications to φ3 and φ4 theories are discussed as illustrations and compared with variational coherent-state analyses.
