• Abstract: Nonlinear magnetoelectric effect(NME) in alkali atomic vapor has applications in precision magnetometry in the radio-frequency domain. We report the application of the NME in alkali atomic vapors for projective measurement of medium-frequency (MF) magnetic fields in a circular basis with an extinction ratio up to 500:1 . Utilizing a longitudinal static magnetic field, we demonstrate a high-sensitivity technique for characterizing the ellipticity of radio-frequency (RF) magnetic fields which can in turn be used for phase sensitive detection in mid frequency communication. Additionally, we demonstrate the conversion of binary phase shift keyed RF magnetic fields into amplitude modulation of generated optical fields, a versatile receiver for communication using the medium frequency band.

  The oscillating magnetic field produced by unbalanced currents in radio-frequency ion traps induces frequency shifts and sideband transitions that can be harmful to precision spectroscopy experiments. Here, we describe a methodology, based on two-photon spectroscopy, for determining both the strength and direction of RF-induced magnetic fields without modifying any DC magnetic bias field or changing any trap power.

  We develop an in-situ magnetic detection technique at megabar pressures with high sensitivity and sub-microscale spatial resolution. We observe the macroscopic magnetic transition of Fe3O4 in the megabar pressure range from strong ferromagnetism (alpha-Fe3O4) to weak ferromagnetism (beta-Fe3O4) and finally to non-magnetism (gamma-Fe3O4) The presented method can potentially investigate the spin-orbital coupling and magnetism-superconductivity competition in magnetic systems.

  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.
