Non-minimal coupling for spin 3/2 fields
Victor M. Villanueva, Juan A. Nieto, and Octavio Obregon
The problem of the electromagnetic coupling for spin 3/2 fields is discussed. Following supergravity and some recent works in the field of classical supersymmetric particles, we fi…
Quantum bounds for gravitational de Sitter entropy and the Cardy-Verlinde formula
Shin'ichi Nojiri, Octavio Obregon, Sergei D. Odintsov +2
We analyze different types of quantum corrections to the Cardy-Verlinde entropy formula in a Friedmann-Robertson-Walker universe and in an (anti)-de Sitter space. In all cases we s…
Cosmological constant and Brane New World
Shin'ichi Nojiri, Octavio Obregon, Sergei D. Odintsov
The estimation of the cosmological constant in inflationary Brane New World models is done. It is shown that basically it is quite large, of the same order as in anomaly-driven inf…
String versus Einstein frame in an AdS/CFT induced quantum dilatonic brane-world universe
Shin'ichi Nojiri, Octavio Obregon, Sergei D. Odintsov +1
AdS/CFT induced quantum dilatonic brane-world where 4d boundary is flat or de Sitter (inflationary) or Anti-de Sitter brane is considered. The classical brane tension is fixed but…
