A Trojan wave packet is a concept that emerges in the context of wave phenomena and nonlinear dynamics. In particular, it refers to a type of wave packet that can be found in certain nonlinear systems, such as those described by the nonlinear Schrödinger equation or similar equations in physics. The term is often associated with situations in which a localized wave packet can exist in a medium without dispersing, appearing to be stable even in a nonlinear environment.
