  • Title: Generation of entangled photons in graphene in a strong magnetic field.
    Author: Tokman M, Yao X, Belyanin A.
    Journal: Phys Rev Lett; 2013 Feb 15; 110(7):077404. PubMed ID: 25166408.
    Abstract:
    Entangled photon states attract tremendous interest as the most vivid manifestation of nonlocality of quantum mechanics and also for emerging applications in quantum information. Here we propose a mechanism of generation of polarization-entangled photons, which is based on the nonlinear optical interaction (four-wave mixing) in graphene placed in a magnetic field. Unique properties of quantized electron states in a magnetized graphene and optical selection rules near the Dirac point give rise to a giant optical nonlinearity and a high rate of photon production in the mid- or far-infrared range. A similar mechanism of photon entanglement may exist in topological insulators where the surface states have a Dirac-cone dispersion and demonstrate similar properties of magneto-optical absorption.
