Vardeny, Zeev Valentine | Electroabsorption spectroscopy of luminescent and nonluminescent ∏-conjugated polymers | We have measured the quadratic electroabsorption (EA) spectrum of a variety of soluble luminescent and nonluminescent p-conjugated polymer films in the spectral range of 1.5-4.5 eV. The luminescent polymers include MEH and DOO derivatives of poly(phenylene-vinylene), poly(phenylene ethylene), and ... | Electroabsorption spectroscopy; pi-conjugated polymers | 1997-12 |

DeTar, Carleton | Exotic mesons in quenched lattice QCD | Since gluons in QCD are interacting fundamental constituents just as quarks are, we expect that in addition to mesons made from a quark and an antiquark, there should also be glueballs and hybrids ~bound states of quarks, antiquarks, and gluons!. In general, these states would mix strongly with th... | Hybrid mesons; Antiquarks | 1997-12 |
