Breathing solitons are nonlinear waves in which the energy concentrates a localized and oscillatory fashion. Similarly to stationary solitons, breathers dissipative systems can form stable bound states displaying molecule-like dynamics, frequently called breather molecules. So far, experimental observation of optical molecules real-time detection their dynamics limited diatomic molecules, that ...

Large parts of the periodic table cannot be cooled by current laser-based methods. We investigate whether zero energy fragmentation of laser cooled fluorides is a potential source of ultracold fluorine atoms. We report new ab initio calculations on the lowest electronic states of the BeF diatomic molecule including spin-orbit coupling, the calculated minima for the valence electronic states bei...

Two examples of application of nonlinear control methods to control of molecular motion are studied. Firstly, the problem of controlling quantum observables for a finite dimensional model of a diatomic molecule is examined and a new control law is obtained based on speed-gradient approach. A substantial domain of initial conditions in the phase space ensuring achievement of the control goal is ...

The time-dependent fluorescence of a model dye molecule in a nanoconfined solvent is used to test approximations based on the dynamic and static linear-response theories and the assumption of Gaussian statistics. Specifically, the results of nonequilibrium molecular-dynamics simulations are compared to approximate expressions involving time correlation functions obtained from equilibrium simula...

This work communicates cavity ring-down spectroscopy (CRDS) of methylidyne (CH) in a chemiluminescent plasma that is produced microwave cavity. Of interest are the rotational lines 0-0 vibrational transition for A–X band and 1-0 B–X band. The reported investigations originate from research on CH radical 1996, which constituted first case applying CRDS to radical. report also includes recent ana...
