interacting O ( N ) scalar theory in curved spacetime
A derivation of the one-loop e ective Lagrangian in the self-interacting O(N) scalar theory, in slowly varying gravitational elds, is presented (using -regularization and heat-kernel techniques). The result is given in terms of the expansion in powers of the curvature tensors (up to quadratic terms) and their derivatives, as well as in derivatives of the background scalar eld (up to second deri...
متن کاملRenormalization-group improved effective potential for interacting theories with several mass scales in curved spacetime
The renormalization group (RG) is used in order to obtain the RG improved effective potential in curved spacetime. This potential is explicitly calculated for the Yukawa model and for scalar electrodynamics, i.e. theories with several (namely, more than one) mass scales, in a space of constant curvature. Using the λφ-theory on a general curved spacetime as an example, we show how it is possible...
متن کاملEffective Lagrangian for self-interacting scalar field theories in curved spacetime.
We consider a self-interacting scalar field theory in a slowly varying gravitational background field. Using zeta-function regularization and heat-kernel techniques, we derive the one-loop effective Lagrangian up to second order in the variation of the background field and up to quadratic terms in the curvature tensors. Specializing to different spacetimes of physical interest, the influence of...
متن کاملRenormalization-group improved effective Lagrangian for interacting theories in curved spacetime
A method for finding the renormalization group (RG) improved effective Lagrangian for a massive interacting field theory in curved spacetime is presented. As a particular example, the λφ-theory is considered and the RG improved effective Lagrangian is explicitly found up to second order in the curvature tensors. As a further application, the curvature-induced phase transitions are discussed for...
متن کاملBose-Einstein condensation for a self-interacting theory in curved spacetime
The effective action is derived for a self-interacting theory with a finite fixed O(2) charge at finite temperature in curved spacetime. We obtain the high temperature expansion of the effective action in the weak coupling limit. In the relativistic temperature, we discuss about the phase transition in a homogeneous spacetime.
