Periodic strings: a mechanical analogy to photonic and phononic crystals
R. S. Pitombo, M. Vasconcellos, P. P. Abrantes +3
We study a periodic vibrating string composed of a finite sequence of string segments connected periodically, with each segment characterized by a constant linear mass density. The…
Controlling the atom-sphere interaction with an external electric field
P. P. Abrantes, V. Pessanha, Reinaldo de Melo e Souza +1
We investigate the system constituted by a polarizable atom near a nanosphere under the influence of an external electrostatic field, showing that the attractive dispersive force b…
Photonic Counterparts of Cooper Pairs
Andre Saraiva, Filomeno S. de Aguiar Junior, Reinaldo de Melo e Souza +5
The microscopic theory of superconductivity raised the disruptive idea that electrons couple through the elusive exchange of virtual phonons, overcoming the strong Coulomb repulsio…
