R. G. Herb Condensed Matter Seminar
Raman scattering in molecular junctions
Time: 10:00 am
Place: 5310 Chamberlin
Speaker: Michael Galperin, University of California, San Diego
Abstract: Recent advances in experimental techniques at nanoscale, and in particular Raman scattering measurements on current-carrying single molecule junctions promises to become a superior diagnostic tool. Theoretical understanding of optical response of open molecular systems far from equilibrium is of major importance for development of molecular optoelectronic devices. Within simple models we consider intra-molecular and charge-transfer contributions to Raman spectroscopy of molecular junction. We also discuss a concept of "effective temperature", its relevance in representation of bias-induced heating, and ability of Raman measurements to provide information on the latter.

High Energy Seminar
Higgs Results From ATLAS
Time: 3:00 pm
Place: 4274 Chamberlin
Speaker: Bruce Mellado, University of Wisconsin Madison
Abstract: The ATLAS Collaboration reported an excess of events with the
H to gammagamma,ZZ channels in December 2011. Results of the low
mass Higgs boson search with channels that were not reported
then will be reviewed. Results with the H to WW,tautau,bbar
channels and their combination with results reported earlier will
be discussed.
