A Novel phase in the phase structure of the $(g{\varphi }^4+h{\varphi }^6{)}_{1+1}$ field theoretic model

Abouzeid M. Shalaby

In view of the newly discovered and physically acceptable $PT$ symmetric and non-Hermitian models, we reinvestigated the phase structure of the ($g{\varphi }^4+h{\varphi }^6$)${}_{1+1}$ Hermitian…
