Quantum Spin of Elastic Wave [PDF]
, 2018 Unveiling intrinsic spins of propagating waves usually offers people a fundamental understanding of the geometrical and topological properties of waves from classical to quantum aspects. A great variety of research has shown that transverse waves can possess non-trivial quantum spins and topology without help of strong wave-matter interaction. However,

Collective Excitonic Assembly in Perovskite Superlattice
Laser &Photonics Reviews, EarlyView.Schematic depiction of CESF, illustrating that once the excitation laser density surpasses the threshold, the whispering gallery mode is initiated, resulting in the appearance of the CESF effect with an increase in collective dipole density. Time evolution of coherence properties under two‐beam excitation for delay times tD<0.1$t_D<0.1$ ps in CESF ...

Stability of Solitary Waves for Three Coupled Long Wave - Short Wave Interaction Equations [PDF]
arXiv, 2009 In this paper we consider a three-component system of one dimensional long wave-short wave interaction equations. The system has two-parameter family of solitary wave solutions. We prove orbital stability of the solitary wave solutions using variational methods.
