Informationentropic measure of energydegenerate kinks in twofield models
Here, we investigate the existence and properties of kinklike solitons in a class of models with two interacting scalar fields. In particular, we focus on models that display both double and singlekink solutions, treatable analytically using the Bogomol'nyi–Prasad–Sommerfield bound (BPS). Such models are of interest in applications that include Skyrmions and various superstringmotivated theories. Exploring a region of parameter space where the energy for very different spatiallybound configurations is degenerate, we show that a newlyproposed momentum–space entropic measure called Configurational Entropy (CE) can distinguish between such energydegenerate spatial profiles. This informationtheoretic measure of spatial complexity provides a complementary perspective to situations where strictly energybased arguments are inconclusive.
