A general electrodynamical theory of a high-Q optical microsphere resonator in an external alternating magnetic field is reported. We show that such a system can change a polarization state of the whispering-gallery-mode photons confined in the sphere due to the Faraday effect. This property can be used in all-optical switches and logical devices. The contribution of the Kerr nonlinearities is also discussed. © 2002 American Institute of Physics.

    Spin depolarizing resonances due to coupling may account for as much as a 30 percent loss in polarization in the AGS. The major source of coupling in the AGS is the solenoidal snake. In the past some preliminary work was done to understand this phenomena [1], and a method to overcome these...

    We experimentally investigate the polarisation dependence of the locking bandwidth and transfer of amplitude modulation within an injection locked laser system. We find that the measured locking bandwidth of our injection locked laser varies by a factor of 2 as a function of polarisation. The...

    An 11.4% partial Siberian snake was used to successfully accelerate polarized protons through a strong intrinsic depolarizing spin resonance in the AGS. No noticeable depolarization was observed. This opens up the possibility of using a 20% to 30% partial Siberian snake in the AGS to overcome...

    A new, compact (approximately fist sized), efficient electron-spin analyzer is described. It is based on low-energy (150 eV) diffuse scattering from a high-Z target, for example, an evaporated polycrystalline Au film opaque to the incident electron beam. By collecting a large solid angle of...

    We present a general description of electron spin polarization observed for interacting radical pairs. Unlike previous treatments, both chemically induced dynamic electron polarization and correlated radical pair polarization are included for ST0 mixing. A key feature of this model is that the...

    [sup 19]F→[sup 23]Na triple quantum (TQ) cross polarization (TQCP) experiments and numerical simulations have been performed on the oxyfluoride NaMoO[sub 3]F. Due to the orientation dependence of the quadrupolar tensor and thus the TQ nutation frequency (ω[sub s,nut]), only a fraction...

    The miscibility of blends of polymethyl methacrylate (PMMA) and polyvinylidene fluoride (PVF2) is investigated using triple resonance 1H–19F–13C cross polarization magic angle spinning nuclear magnetic resonance (CPMAS NMR). Two techniques are introduced which give information on...

    A theoretical analysis is made of the conversion of the polarization of an electromagnetic wave when cyclotron resonance is excited in a two-dimensional electron system. It is shown that the greatest conversion of the polarization can be achieved in the reflected wave. At high electron...
