Dual coherent particle emission as generalized two-component Cherenkov-like effect

In this Letter we introduce a new kind of coherent particle production mechanism called dual coherent particle emission (DCPE) as generalized two-component Cherenkov-like effect, which takes place when the phase velocity of emitted particle v_{Mph} and the particle source phase velocity v_{B_1ph} satisfy a specific DCPE condition: v_{Mph}
