1 Gondolo, PaoloCan WIMP spin dependent couplings explain DAMA data, in light of null results from other experiments?We examine whether the annual modulation found by the DAMA dark matter experiment can be explained by Weakly Interacting Massive Particles (WIMPs), in light of new null results from other experiments. CDMS II has already ruled out most WIMP-nucleus spin-independent couplings as an explanation for DA...WIMP; Weakly interacting massive particles; DAMA; CDMS II; Parameter space2004-12
2 Lupton, John MarkExperimental evidence for exciton scaling effects in self-assembled molecular wiresResonant Rayleigh scattering from self-assembled one-dimensional molecular J-aggregate wires reveals a distinct dependence of the exciton energy on the width of lateral extension. For the J aggregates used in this study, strong in-line dipole coupling leads to a delocalization of the exciton wave fu...Exciton scaling effects; Molecular wires; J-aggregate wires; Quantum wires2004-12
3 DeTar, CarletonLight pseudoscalar decay constants, quark masses, and low energy constants from three-flavor lattice QCDAs part of our program of lattice simulations of three-flavor QCD with improved staggered quarks, we have calculated pseudoscalar meson masses and decay constants for a range of valence quark masses and sea-quark masses on lattices with lattice spacings of about 0.125 and 0.09 fm. We fit the lattic...Staggered quarks; Chiral symmetry; Perturbation theory2004-12
4 Vardeny, Zeev ValentineSpectroscopic study of spin-dependent exciton formation rates in ∏-conjugated semiconductors: comparison with electroluminescence techniquesIt has been found in recent measurements that the singlet-to-triplet exciton ratio in organic light-emitting diodes (OLEDs) is larger than expected from spin degeneracy, and that singlet excitons form at a larger rate than triplets. We employed the technique of optically detected magnetic resonance...Spin-dependent exciton formation; pi-conjugated polymers2004-12
5 Furse, Cynthia M.Take a Stand: Speaking about RF SafetyTell your students at the beginning of the semester that they need to prepare a speech and deliver it before an off-campus audience, and they will not exactly be leaping out of their seats with joy. Remind them a week in advance that their speech is coming up, and you will inevitably have a student ...Radio frequency safety; RF safety2004-12
