Classical and quantum integrability in 3D systems
M. Gadella, J. Negro, G. P. Pronko +1
In this contribution, we discuss three situations in which complete integrability of a three dimensional classical system and its quantum version can be achieved under some conditi…
On the applications of Hardy class functions in scattering theory
M. Gadella, S. Wickramasekara
This paper is a response to an article (R. de la Madrid, Journal of Physics A: Mathematical and General, 39,9255-9268 (2006)) recently published in Journal of Physics A: Mathematic…
Riggings of locally compact abelian groups
M. Gadella, F. Gomez, S. Wickramasekara
We obtain a set of generalized eigenvectors that provides a generalized spectral decomposition for a given unitary representation of a commutative, locally compact topological grou…
The Friedrichs-Model with fermion-boson couplings II
O. Civitarese, M. Gadella, G. P. Pronko
In this work we present a formal solution of the extended version of the Friedrichs Model. The Hamiltonian consists of discrete and continuum bosonic states, which are coupled to f…
The Friedrichs-Model with fermion-boson couplings
O. Civitarese, M. Gadella
In this work we present an extended version of the Friedrichs Model, which includes fermion-boson couplings. The set of fermion bound states is coupled to a boson field with discre…
Classical and quantum three-dimensional integrable systems with axial symmetry
M. Gadella, J. Negro, G. P. Pronko
We study the most general form of a three dimensional classical integrable system with axial symmetry and invariant under the axis reflection. We assume that the three constants of…
