Effect of spatial-phase drift on the synchronization of swarmalators with higher-order interactions
Model
Unlike one-dimension oscillator model, we considered a pair of mutually coupled Kuramoto models, referred to as spatial-phase oscillator (swarmalator)46. The interaction between swarmalators is influenced not only by their phases but also by…

Solving perfect matchings by frequency-grouped multi-photon events using a silicon chip
Theoretical description
Broadband photon-pair source can be realized by χ(2) nonlinear processes such as spontaneous parametric down-conversion, or χ(3) nonlinear process such as spontaneous four-wave mixing(SFWM). We take SFWM on the silicon…
