• Abstract: We suggest a scheme of electromagnetic chirality-induced negative refraction utilizing magneto-electric cross coupling in a four-level atomic system. The negative refraction can be achieved with the two chirality coefficients having the same amplitude but the opposite phase,and without requiring the simultaneous presence of an electric-dipole and a magnetic-dipole transition near the same transition frequency. The simultaneously negative electric permittivity and magnetic permeability does not require, either.

  The negative refractive index without simultaneously negative permittivity and permeability can be obtained when the argument is in the second quadrant of the cartesian coordinate system. As an application, our scheme may possibly give a novel approach to obtain negative refractive index by electromagnetic chirality-inducing.

  We analyse the effect of a strong perpendicular magnetic field on an intersubband transition in a disordered doped quantum well strongly coupled to an optical cavity. The magnetic field changes the lineshape of the intersubband optical transition due to the roughness of the interface of the quantum well from a Lorentzian to a Gaussian one.

  Recent experiments have demonstrated strong light-matter coupling between electromagnetic nanoresonators and pristine sheets of two-dimensional semiconductors. We present a first-principles microscopic quantum theory for the interaction between excitons in an infinite sheet of two-dimensional material and a localised electromagnetic resonator. We predict that polariton blockade due to nonlinear exciton-exciton interactions is well within reach for nanoresonators coupled to transition-metal dichalcogenides.

  We report the existence of a sizeable quantum tunnelling splitting between the two lowest electronic spin levels of mononuclear Ni complexes. The level anti-crossing, or magnetic clock transition, associated with this gap has been directly monitored by heat capacity experiments. The comparison of these results with those obtained for a Co derivative, for which tunnelling is forbidden by symmetry, shows that the clock transition leads to an effective suppression of intermolecular spin-spin interactions.
