Can an optical wavepacket localize in both space and time? We seek these ‘event solitons’ through the balance of mixed gaps and nonlinearity.

Where do correlated photon pairs come from? This theoretical work connects temporal boundaries with gap amplification to explore photon correlations after a k-gap soliton exits the medium.

A breathing event can emerge in an unstable optical field, drawing energy from competing solitons; its rhythm can be tuned by a seed signal.

At the quantum scale, k-gap solitons involve photon pairs, collapse and revival, and nonclassical interference.

Tuning the relative phase allows two amplified optical waves to cancel. Their pattern may evolve superluminally without transmitting information faster than light.
