Circularly polarized optical excitation of plasmonic nanostructures causes coherent circulating motion of their electrons, which in turn, gives rise to strong optically induced magnetization - a phenomenon known as the inverse Faraday effect (IFE). I

Dark solitons of a two-component condensate occurring in nonresonantly-pumped microcavity polaritons (spinor MPCs) with integer vorticities, referred to as integer dark solitons (IDSs), can be excited by a laser beam with tunable polarization and pow

Twin-core optical fibers are applied in the fiber optic sensing technique and optical communication. Non-Kerr media are seen in plasma physics, nonlinear quantum mechanics and nonlinear optics. Propagation of an optical beam and superradiance for an

A ring-vortex soliton (RVS) is unstable in a uniform microcavity polariton condensate (MPC). We propose a method for generating a stable RVS in an MPC subjected to a ring-shaped defect potential. The density distribution of a RVS with a pump strength

We study a localized polaritonic state with nonequilibrium and nonlinear characters at a surface created by two mismatched and semi-infinite potentials in exciton-polariton condensates. We find that the localized polaritonic state exists only when th

As a new analytical method to identify oil spill on the sea, the main effect of polarization measurement based on Mueller matrix is extracting surface feature of oil film, so that the polarization information of the target can be enriched. In this pa

A spontaneously formed vortex can occur in an incoherently pumped microcavity-polariton condensate which is a non-equilibrium system. The stability of this vortex depends on the flux quanta that the vortex owns. In this paper, we have investigated th

We describe an unsaturated gain-loss model in regards to colloidal PbSe quantum dot (QD)-doped fiber laser realized previously. Based on experimental observation on the laser, the numerical simulation on the model indicates there exists a pumping thr

We study the dynamics of spontaneously formed vortices in incoherently pumped homogeneous microcavity polariton condensates (MPC). We find vortices are stable and appear spontaneously without stirring or rotating MPCs by the numerical modeling using

The dark polariton solitons are investigated in a 1D periodic potential. The effective-mass approximation is used to obtain the numerical dark solitons in the zone center and edge under a diversity of potential depths and pump powers.
