On the consequences of the fact that atomic levels have a certain width
Claude Billionnet
This note presents two ideas. The first one is that quantum theory has a fundamentally perturbative basis but leads to nonperturbative states which it would seem natural to take in…
Resonances for a Hydrogenic System or a Harmonic Oscillator Strongly Coupled to a Field
Claude Billionnet
We calculate resonances which are formed by a particle in a potential which is either Coulombian or quadratic when the particle is strongly coupled to a massless boson, taking only…
Influence of the extent of the eigenstates of a system on the resonances formed through its coupling to a field
Claude Billionnet
We examine resonances for two systems consisting of a particle coupled to a massless boson's field. The field is the free field in the whole space. In the first system, the particl…
Weak and strong coupling regimes, vacuum Rabi splitting and nonstandard resonances
C. Billionnet
For two discrete-level quantum systems in interaction, we follow the displacement in the complex plane of the eigen-energies of the compound system when the spectrum of one of the…
On hybrid states of two and three level atoms
C. Billionnet
We calculate atom-photon resonances in the Wigner-Weisskopf model, admitting two photons and choosing a particular coupling function. We also present a rough description of the set…
