Influência conjunta da polarização e da coerência da luz no experimento da dupla fenda sob uma perspectiva quântica

Abstract

In this research, we studied the wave-particle duality through quantifiers of visibility and distuinguishability by the complementary principle. We used the unified density matrix formalism of coherence and polarization as the basis for this study. If we have information on the path, the interference pattern is destroyed and the photon behaves like a particle, on the other hand, a maximum contrast pattern is verified when there is no information on the path taken, a wave-like behavior. To witness the wave-particle duality using the visibility V and distinguishability D quantifiers derived in the research, we present several physical examples and show that it is possible to verify the behavior of photons, quantified through the principle of complementarity by means of the inequality D2 + V 2 ≤ 1.
