Beam Foil

The results are summarised of previous experiments on the beam-foil excitation of Rydberg states of Br ions containing L vacancies. These show two populations, namely one with high angular momentum .e leading to 'yrast' cascades, and a separate low-.e population. Models for the production of such states in solid targets are discussed, and experiments to test the predictions of these models are described. The target-thickness dependence and downstream decay of the 'yrast' states is consistent with a standard charge-changing and capture model. The low-.e population is very sensitive to the presence of an applied electric field, and it is concluded that such Rydberg states are partly created by the radiative recapture of free 'convoy' electrons which travel physically near their host ions. Detailed level and decay schemes are described for the Br2S+, Ne-like system.

Abstract We theoretically investigate quantum entanglement and coherence in a hybrid Laguerre-Gaussian rotating cavity optomechanical system with two-level atoms, where cavity and mechanical modes are coupled through the exchange of orbital angular momentum. Our study shows that the injection of atoms with a suitable choice of the physical parameters can significantly improve the degree of optomechanical entanglement in all aspects. In the study of quantum coherence research, we show more comprehensively the negative and positive effects of atoms on the coherence. The result obtained is that only when the atom is significantly offresonant to driving field, the coupling strength in between the atoms and light field increases and the quantum coherence can be enhanced, otherwise it will reduce quantum coherence. In addition, the atomic decay suppresses quantum coherence phenomenon.
