On the local term in the anomaly-induced action of Weyl quantum gravity

Andrei O. Barvinsky, Guilherme H. S. Camargo, Alexei E. Kalugin +2

The finite local conformally non-invariant -term emerges in the one-loop effective action of the model of quantum gravity based on the Weyl-squared classical action. This term…

Anomaly-induced vacuum effective action with torsion: covariant solution and ambiguities

Guilherme H. S. Camargo, Ilya L. Shapiro

The conformal anomaly in curved spacetime with antisymmetric torsion is reconsidered, taking into account new important details. We formulate, for the first time, the covariant sol…

Anisotropic motion of an electric dipole in a photon gas near a flat conducting boundary

G. H. S. Camargo, V. A. De Lorenci, A. L. Ferreira Junior +1

The quantum Brownian motion of a single neutral particle with nonzero electric dipole moment placed in a photon gas at fixed temperature and close to a conducting wall is here exam…

Probing thermal fluctuations through scalar test particles

G. H. S. Camargo, V. A. De Lorenci, A. L. Ferreira Junior +1

The fundamental vacuum state of quantum fields, related to Minkowski space, produces divergent fluctuations that must be suppressed in order to bring reality to the description of…

Vacuum induced dispersions on the motion of test particles in dimensions

G. H. S. Camargo, V. A. De Lorenci, C. C. H. Ribeiro +1

When the vacuum state of a scalar or electromagnetic field is modified by the presence of a reflecting boundary, an interacting test particle undergoes velocity fluctuations. Such…

Vacuum fluctuations of a scalar field near a reflecting boundary and their effects on the motion of a test particle

G. H. Camargo, V. A. De Lorenci, C. C. H. Ribeiro +2

The contribution from quantum vacuum fluctuations of a real massless scalar field to the motion of a test particle that interacts with the field in the presence of a perfectly refl…
