Generation and manipulation of multipole and vortex events in (1+1)-dimensional spacetime
Yiming Pan, Guowei Chen
An event is usually regarded as a zero-dimensional coordinate label in spacetime, rather than as an object with spatial extent, internal structure or topology. Here we show that in…

Time domain Stokes mechanism of pair correlated k gap solitons in nonlinear photonic time crystal slabs
Jiaxiang Sun, Guowei Chen, Liang Zhang +1
Pair generation in time-varying media is commonly attributed to time reflection at temporal boundaries or to amplification inside momentum k gaps. Here we show that these two proce…
