Optomechanically-induced transparency (OMIT) and the associated slowing of light provide basis for storing photons in nanoscale devices. Here we study OMIT parity-time (PT)-symmetric microresonators with a tunable gain-to-loss ratio. This system features reversed, non-amplifying transparency, i.e., an inverted-OMIT. When ratio is varied, exhibits transition from PT-symmetric phase to broken-PT-symmetric phase. PT-phase results reversal pump gain dependence transmission rates. Moreover, show...
Recently, Pu et al. developed an efficient strategy to find the adiabatic condition of a nonlinear system---i.e., atom-homonuclear dimer conversion [Phys. Rev. Lett. 98, 050406 (2007)]. Here, by applying their method, we extend it study coherent atom--heteronuclear-diatomic- or -triatomic-molecule conversion. The different evolutions in creating homo- heteronuclear dimers are compared. impact two reaction paths on conditions triatomic molecules is also discussed.
We investigate the coherent two-color photoassociation (PA) process in a spinor-1 atomic Bose-Einstein condensate by comparing single-spin and mixed-spin cases. find that, tuning PA light applied on different spin components, one can observe quite features for spin-mixing dynamics (with weak field) or atom-molecule conversion strong field), indicating research field of so-called superchemistry spinor gas.
Abstract Based on first-principles calculations, the structural, mechanical, electronic, and optical properties of K 2 TiBr 6 , an ordered double perovskite with numerous titanium base positions, are investigated under pressure conditions from 0 to 150 GPa. This research seeks thoroughly study changes in physical caused by evaluate applicability compound optoelectronic applications. The structural characteristic fits well published earlier research. A higher interaction between atoms is also...
We study the quantum dynamics of coherent creation triatomic molecules from a repulsive atomic Bose-Einstein condensate. In single-mode approach with short pulse duration we consider squeezing effects for homonuclear and heteronuclear trimers by taking into account an optical photoassociation. The possibility manipulating statistical properties trimer fields provides appealing research area current molecular matter-wave optics.
