Approximating the two-mode two-photon Rabi model

Two-Photon Entanglement in a Two-Mode Supersymmetric Model

We will study entangled two-photon states generated from a two-mode supersymmetric model and quantify degree of entanglement in terms of the entropy of entanglement. The influences of the nonlinearity on the degree of entanglement is also examined, and it is shown that amount of entanglement increase with increasing the nonlinear coupling constant.

The Two-Photon Decay Mode of MSSM Higgs Bosons

At the Large Hadron Collider (LHC), the CP-even Higgs bosons (h and H) of the Minimal Supersymmetric Standard Model (MSSM) will be searched for mainly through their two-photon decay. We present a detailed analysis of the production and two-photon decay of the CP-even Higgs bosons of MSSM at the LHC by taking into account all the parameters of the model, especially the bilinear parameter μ and t...

Quadratic Lie algebras and quasi-exact solvability of the two-photon Rabi Hamiltonian

It is proved that the two-photon Rabi Hamiltonian is quasi exactly solvable on the basis of the two different quadratic Lie algebras.

TWO PHOTON TRANSITIONS IN THE OPTOGALVANIC SPECTRUM OF NEON

Seventeen two-photon transitions for neon have been observed in the 580- 635 nm spectral region for use in the spectroscopic study of its higher excited levels, which are not accessible by one-photon absorption. To compare the two and one-photon absorption signals originating from the same lower level, an effort was made to record single-photon optogalvanic spectrum in the available wavele...
