Aspects and applications of quantum field theory on spaces with conical singularities
Devis Iellici
One-loop effects for quantum fields living on manifolds containing conical singularities are investigated in the context of cosmic string background and of finite-temperature theor…
zeta-function regularization and one-loop renormalization of field fluctuations in curved space-times
Valter Moretti, Devis Iellici
A method to regularize and renormalize the fluctuations of a quantum field in a curved background in the -function approach is presented. The method produces finite quantities d…
Massive scalar field near a cosmic string
Devis Iellici
The 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 energ…
Kabat's Surface Terms in the Zeta-Function approach
Devis Iellici, Valter Moretti
The thermal partition functions of photons in any covariant gauge and gravitons in the harmonic gauge, propagating in a Rindler wedge, are computed using a local zeta-function appr…
Optical Approach for the Thermal Partition Function of Photons
Valter Moretti, Devis Iellici
The optical manifold method to compute the one-loop effective action in a static space-time is extended from the massless scalar field to the Maxwell field in any Feynman-like cova…
Thermal partition function of photons and gravitons in a Rindler wedge
Devis Iellici, Valter Moretti
The thermal partition function of photons in any covariant gauge and gravitons in the harmonic gauge, propagating in a Rindler wedge, are computed using a local -function regula…
