Dark-State Interference in an Effective Confined Three-Level Color System
Abstract
In this work, a QCD-inspired effective model describes dark-state interference in a confined three-state system with two low-energy QQ̅ states, |1⟩ and |2⟩, and a gluon-excited hybrid state, |H⟩. A stationary chromoelectric flux-tube background enters the unperturbed Hamiltonian, while a time-dependent chromoelectric perturbation couples |1⟩ and |2⟩ to |H⟩ in a Λ-type configuration. Under two-photon\footnote{We retain standard terms like ``two-photon'' from the EIT literature only by mathematical analogy, but they do not refer to electromagnetic photons but to the effective frequencies and energy mismatches of chromoelectric perturbations and gluonic excitations that connect confined states.} resonance and within a Markovian Gorini-Kossakowski-Sudarshan-Lindblad master equation, the system forms a coherent superposition that decouples from |H⟩, strongly suppressing the steady-state probe susceptibility ImχCE as lower-state decoherence vanishes. A phenomenological non-Abelian correction to the hybrid energy mainly shifts and reshapes the transparency window rather than creating the interference itself. The model is not a first-principles QCD calculation of medium opacity but a controlled effective link between dark-state interference in quantum optics and reduced confined color dynamics.
