In this paper, we initiate the study of operator local quenches in non-conformal field theories. We consider dynamics excited states massive scalar theory an arbitrary spacetime dimension and generalize well-known two-dimensional CFT results. derive energy density, $U(1)$-charge density $\phi^2(x)$-condensate post-quench dynamics, identify different regimes their evolution depending on values m...
In this paper, the effective field theory for the anisotropic inflationary universe in Weinberg's approach is studied. We consider the leading correction terms to the standard interactions in the anisotropic inflationary models. These consist of forth derivative of the fields, scalar field, gauge field and metric. Then, the scalar power spectrum is investigated in the presence of higher energy ...
We present the Heisenberg-picture approach to the quantum evolution of the scalar fields in an expanding FRW universe which incorporates relatively simply the initial quantum conditions such as the vacuum state, the thermal equilibrium state, and the coherent state. We calculate the Wightman function, two-point function, and correlation function of a massive scalar field. We find the quantum ev...
