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…
Connes-Lott model building on the two-sphere
J. A. Mignaco, C. Sigaud, A. R. da Silva +1
In this work we examine generalized Connes-Lott models on the two-sphere. The Hilbert space of the continuum spectral triple is taken as the space of sections of a twisted spinor b…
The Connes-Lott program on the sphere
J. A. Mignaco, C. Sigaud, A. R. da Silva +1
We describe the classical Schwinger model as a study of the projective modules over the algebra of complex-valued functions on the sphere. On these modules, classified by $π_2(S^2)…
