Amplification of the scattering cross section due to non-trivial topology of the spacetime
K. Kirsten, Yu. Kubyshin
In previous articles it was demonstrated that the total cross section of the scattering of two light particles (zero modes of the Kaluza-Klein tower) in the six-dimensional $λϕ^{4}…
On the instability of the vacuum in multidimensional scalar theories
E. Elizalde, K. Kirsten, Yu. Kubyshin
The 1-loop effective potential in a scalar theory with quartic interaction on the space for is calculated and is shown to be unbounded from below. This i…
Are p-Branes Asymptotically Black Holes?
Andrei Bytsenko, Klaus Kirsten, Sergio Zerbini
An attempt is made to compare the asymptotic state density of twisted -branes and the related state density of mass level of a -dimensional neutral black hole. To this ai…
Effective Lagrangian and the back-reaction problem in a self-interacting scalar theory in curved spacetime
Emilio Elizalde, Klaus Kirsten, Sergei Odintsov
A derivation of the one-loop effective Lagrangian in the self-interacting scalar theory, in slowly varying gravitational fields, is presented (using -regularization and h…
One-loop effective potential in 2D dilaton gravity on hyperbolic plane
Klaus Kirsten, Sergei Odintsov
The one-loop effective potential in dilaton gravity in conformal gauge on the topologically non-trivial plane and on the hyperbolic plane is calcul…
