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…
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…
