Critical Coupling in (1+1)-Dimensional Light-Front $ϕ^{4}$ Theory. II -effects of non-diagonal interactionof non-diagonal interactions-

Kazuto Oshima

Spontaneous symmetry breaking in (1+1)-dimensional $ϕ^{4}$ theory is studied with discretized light-front quantization. Taking effects of non-diagonal interactions into account, th…

Gap Equations of O(N) Non-linear Sigma Model in Three Dimensions

Kazuto Oshima

We study the $O (N)$ non-linear $σ$ model on three-dimensional manifolds of constant curvature by means of the large $N$ expansion at the critical point. We examine saddle point equ…
