A Trojan wave packet is a wave packet that is nonstationary and nonspreading. It is part of an artificially created system, which consists of a nucleus, and one or more electron wave packets, of a highly excited atom. A strong, polarized electromagnetic field, holds or traps" each electron wave packet in an intentionally selected orbit (energy shell). They derive their names from the Trojan asteroids in the Sun-Jupiter system. Trojan asteroids orbit around the sun in Jupiter''s orbit at its Lagrangian equilibrium points L4 and L5, where they are phase-locked and protected from collision with each other, and this phenomenon is analogous to the way the wave packet is held together."
