On the spectrum of magnetic Dirac operators with Coulomb-type perturbations

Serge Richard, Rafael Tiedra de Aldecoa

We carry out the spectral analysis of singular matrix valued perturbations of 3-dimensional Dirac operators with variable magnetic field of constant direction. Under suitable assum…

Generalized definition of time delay in scattering theory

C. Gerard, R. Tiedra de Aldecoa

We advocate for the systematic use of a symmetrized definition of time delay in scattering theory. In two-body scattering processes, we show that the symmetrized time delay exists…

Spectral analysis for adjacency operators on graphs

M. Mantoiu, S. Richard, R. Tiedra de Aldecoa

We put into evidence graphs with adjacency operator whose singular subspace is prescribed by the kernel of an auxiliary operator. In particular, for a family of graphs called admis…
