A Four-Dimensional Theory for Quantum Gravity with Conformal and Nonconformal Explicit Solutions
E. Elizalde, A. G. Jacksenaev, S. D. Odintsov +1
The most general version of a renormalizable theory corresponding to a dimensionless higher-derivative scalar field model in curved spacetime is explored. The classical actio…
Higher Derivative Four-Fermion Model in Curved Spacetime
E. Elizalde, S. Leseduarte, S. D. Odintsov
We discuss the phase structure of a higher derivative four-fermion model in four dimensions in curved spacetime in frames of the -expansion. First, we evaluate in ou…
Non-Critical Bosonic String Corrections to the Black Hole Entropy
E. Elizalde, S. D. Odintsov
We calculate the quantum corrections to the entropy of a very large black hole, coming from the theory of a -dimensional, non-critical bosonic string. We show that, for ,…
Improved Effective Potential in Curved Spacetime and Quantum Matter - Higher Derivative Gravity Theory
Emilio Elizalde, Sergei D. Odintsov, August Romeo
\noindent{\large\bf Abstract.} We develop a general formalism to study the renormalization group (RG) improved effective potential for renormalizable gauge theories ---including ma…
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…
Manifestations of Quantum Gravityin Scalar QED Phenomena
Emilio Elizalde, Sergei D. Odintsov, August Romeo
Quantum gravitational corrections to the effective potential, at one-loop level and in the leading-log approximation, for scalar quantum electrodynamics with higher-derivative grav…
