The autocorrelation of the Mobius function and Chowla's conjecture for the rational function field
We prove a function field version of Chowla's conjecture on the
autocorrelation of the Mobius function in the limit of a large finite field.Comment: Added background details about discriminants and resultants, and more
minor change
For operation of the Computer Software Management and Information Center (COSMIC)
During the month of June, the Survey Research Center (SRC) at the University of Georgia designed new benefits questionnaires for computer software management and information center (COSMIC). As a test of their utility, these questionnaires are now used in the benefits identification process
Modal Spectroscopy of Optoexcited Vibrations of a Micron-Scale On-Chip Resonator at Greater than 1 GHz Frequency
We analyze experimentally and theoretically >1 GHz optoexcited mechanical vibration in an on-chip micron-scaled sphere. Different eigen-mechanical modes are excited upon demand by the centrifugal radiation pressure of the optical whispering-gallery-mode, enabling an optomechanical modal spectroscopy investigation of many vibrational modes. Spectral analysis of the light emitted from the device enables deduction of its natural vibrational modes in analogy with spectroscopy of a molecule's vibrational levels, and its eccentricity perturbation is shown to induce spectral splitting
Surface optomechanics: Calculating optically excited acoustical whispering gallery modes in microspheres
Stimulated Brillouin scattering recently allowed experimental excitation of
surface acoustic resonances in micro-devices, enabling vibration at rates in
the range of 50 MHz to 12 GHz. The experimental availability of such mechanical
whispering gallery modes in photonic-MEMS raises questions on their structure
and spectral distribution. Here we calculate the form and frequency of such
vibrational surface whispering gallery modes, revealing diverse types of
surface vibrations including longitudinal, transverse, and Rayleigh-type
deformations. We parametrically investigate these various modes by changing
their orders in the azimuthal, radial, and polar directions to reveal different
vibrational structures including mechanical resonances that are localized near
the interface with the environment where they can sense changes in the
surroundings.Comment: 10 pages, 5 figures, 1 table; journal paper - Optics Express,

Tweezers controlled resonator
We experimentally demonstrate trapping a microdroplet with an optical tweezer
and then enabling it as a microresonator by bringing it close to a tapered
fiber coupler. Our tweezers facilitated the tuning of the coupling from the
under-coupled to the critically coupled regime with an optical Q of 12 million
and microresonator size at the 85 mirons scale.Comment: 5 pages, 4 figure
