Dynamical Casimir photons from rotation of a nonspherical particle

Guilherme C. Matos, Lucas Bianchi, Jeremy N. Munday +3

We consider a non-spherical neutral particle spinning in free space and interacting with the electromagnetic quantum vacuum. When the rotation axis is orthogonal to the particle sy…

On the magnetic counterpart of the Uehling correction

T. Azevedo, F. A. Barone, C. Farina +2

In this work, we investigate the magnetic properties of the quantum vacuum in the context of QED. We calculate the quantum relativistic correction of virtual particle-anti-particle…

Microscopic Quantum Friction

Pedro H. Pereira, F. Impens, C. Farina +2

We report on a microscopic theory of quantum friction. Our approach investigates the interplay between the dispersive response and the relative center-of-mass motion of two ground-…

Dispersive interaction between two atoms in Proca Quantum Electrodynamics

Gabriel Camacho de Pinho, Carlos Augusto Domingues Zarro, Carlos Farina +2

We analyze the influence of a massive photon in the dispersive interaction between two atoms in their fundamental states. We work in the context of Proca Quantum Electrodynamics. T…

Dynamical Casimir effects with atoms: from the emission of photon pairs to geometric phases

François Impens, Reinaldo de Melo e Souza, Guilherme C. Matos +1

The coupling between a moving ground-state atom and the quantum electromagnetic field is at the origin of several intriguing phenomena ranging from the dynamical Casimir emission o…

Repulsive van der Waals interaction between a quantum particle and a conducting toroid

P. P. Abrantes, Yuri França, Reinaldo de Melo e Souza +2

We calculate the non-retarded dispersion force exerted on an electrically polarizable quantum particle by a perfectly conducting toroid, which is one of the most common objects exh…

Is the tautochrone curve unique?

Pedro Terra, Reinaldo de Melo e Souza, C. Farina

The answer to this question is no. In fact, in addition to the solution first obtained by Christiaan Huygens in 1658, given by the cycloid, we show that there is an infinite number…

Decoherence by spontaneous emission: a single-atom analog of superradiance

Reinaldo de Melo e Souza, François Impens, Paulo A. Maia Neto

We show that the stationary decoherence rate of an open quantum system can be decomposed as a sum of local and nonlocal contributions, respectively related to the strength of the c…

Image method in the calculation of the van der Waals force between an atom and a conducting surface

Reinaldo de Melo e Souza, W. J. M. Kort-Kamp, C. Sigaud +1

Initially, we make a detailed historical survey of van der Waals forces, collecting the main references on the subject. Then, we review a method recently proposed by Eberlein and Z…

Sommerfeld's image method in the calculation of van der Waals forces

Reinaldo de Melo e Souza, W. J. M. Kort-Kamp, C. Sigaud +1

We show how the image method can be used together with a recent method developed by C. Eberlein and R. Zietal to obtain the dispersive van der Waals interaction between an atom and…

Finite size effects and non-additivity in the van der Waals interaction

Reinaldo de Melo e Souza, W. J. M. Kort-Kamp, C. Sigaud +1

We obtain analytically the exact non-retarded dispersive interaction energy between an atom and a perfectly conducting disc. We consider the atom in the symmetry axis of the disc a…
