- 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.
- Host: Irena Knezevic & Robert Joynt
- 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. - Host: Matthew Herndon
