In this paper, the nonlinear coupled system of partial differential equations named the Wu–Zhang system investigated by applying the new auxiliary equation method. The Wu–Zhang system help us to ...

Natural phenomena are characterized by the presence of many nonlinearities and varying factors. A crucial role is played by non-linear partial differential equations (NLPDEs) as mathematical tools for ...

Scientists from the Faculty of Physics of the University of Warsaw have demonstrated exciton-polariton lasing and parametric scattering of exciton-polaritons in a system of coupled optical ...
