Massive scalar eld near a cosmic
نویسنده
چکیده
The function of a massive scalar eld near a cosmic string is computed and then employed to nd the vacuum uctuation of the eld. The vacuum expectation value of the energy-momentum tensor is also computed using a point-splitting approach. The obtained results could be useful also for the case of self-interacting scalar elds and for the nite-temperature Rindler space theory.

Massive scalar field near a cosmic string
The ζ function of a massive scalar field near a cosmic string is computed and then employed to find the vacuum fluctuation of the field. The vacuum expectation value of the energy-momentum tensor is also computed using a point-splitting approach. The obtained results could be useful also for the case of self-interacting scalar fields and for the finite-temperature Rindler space theory. PACS num...
متن کاملCosmic fluctuations and dark matter from scalar field oscillations.
It is argued that scale-invariant cosmic uctuations and cosmic dark matter might originate from two di erent modes of a single scalar eld. The dynamical relaxation of a multicomponent classical scalar eld in an expanding universe excites two generic types of global modes: massless Goldstone oscillations, which lead to scale-invariant isentropic uctuations, and massive Higgs modes, which lead to...
متن کاملBack Reaction in the Formation of a Straight Cosmic String
A simple model for the formation of a straight cosmic string, wiggly or un-perturbed is considered. The gravitational eld of such string is computed in the linear approximation. The vacuum expectation value of the stress tensor of a massless scalar quantum eld coupled to the string gravitational eld is computed to the one loop order. Finally, the back-reaction eeect on the gravi-tational eld of...
متن کاملFinite temperature correlation function of two dissipative massive scalar fields: Thermofield approach
The present paper aims at investigating the manner of two dissipative massive scalar fields. Two massive scalar fields that interact with a reservoir were considered and a reservoir was modeled by continuum Klein-Gordon fields. The Lagrangian of the total system was canonically quantized and the dynamics of the system was determined using the Euler-Lagrange equation. Then, the explicit form of the...
