• Abstract: Nitrogen-vacancy color centers in diamond have proven themselves as a good, sensitive element for the measurement of magnetic fields. While the mainstream of magnetometers based on NV centers uses so-called optically detected magnetic resonance, there has recently been a suggestion to use dispersive readout of a dielectric cavity to enhance the sensitivity of magnetometers. Here, we demonstrate that the dispersive readout approach can be significantly improved if a two-channel scheme is considered.

  We propose the realization of a nanoscale scanning electron paramagnetic resonance sensor using a vortex core in a thin-film disc. The vortex core can be displaced by using external magnetic fields of a few mT, enabling EPR scanning microscopy with large spatial resolution. Vortex nanocavities could also attain strong coupling to individual spin molecular qubits, with potential applications to mediate qubit-qubit interactions.

  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.
