Wave-Particle duality and an exact triality relation: Manifestation in multi slit interference and Dicke state super/sub radiance

Recently, an exact triality relation has been established in the well studied multi slit interference phenomenon, which surprisingly involves entanglement. Interestingly, this relationship involves the which path information, coherence and a specific geometric measure of entanglement, known as I-concurrence, which has found experimental verification. We demonstrate that, this formalism naturally extends to the description of the transition path ways in the Dicke state, explaining the role of entanglement in the sub and superradiance behaviour of this well studied system.
