Vardeny, Zeev Valentine | Cooperative and stimulated emission in poly(p-phenylene-vinylene) thin films and solutions | We discuss cooperative and stimulated emissions and separate their respective contributions to the emission spectral narrowing in thin films and solutions of poly(p-phenylene-vinylene) derivatives. Whereas cooperative radiation is favored in films with poor optical confinement, directional stimula... | pi-conjugated polymers; PPV; Spectral narrowing | 1998-04 |

DeTar, Carleton | Critical behavior at the chiral phase transition | It is generally expected that two-flavor QCD undergoes a high temperature chiral symmetry restoring phase transition at zero quark mass, with O(4) critical behavior[1]. Verifying this expectation is important for understanding the phenomenology of the transition and for facilitating an extrapolation... | Phase transitions; Staggered fermions | 1998-04 |

DeTar, Carleton | Light quark spectrum with improved gauge and fermion actions | We report on a study of the light quark spectrum using an improved gauge action and both Kogut-Susskind and Naik quark actions. We have studied six different lattice spacings, corresponding to plaquette couplings ranging from 6.8 to 7.9, with five to six quark masses per coupling. We compare the t... | Quark spectrum; Kogut-Susskind quarks; Naik quarks | 1998-04 |

Wu, Yong-Shi | Thermal activation of quasiparticles and thermodynamics of fractional quantum Hall liquids | Quasielectrons and quasiholes in the fractional quantum Hall liquids obey fractional (including nontrivial mutual) exclusion statistics. Their statistics matrix can be determined from several possible state-counting schemes, involving different assumptions on statistical correlations. Thermal activ... | Quasielectrons; Quasiholes; Exclusion statistics | 1998-04 |

DeTar, Carleton | Update on the hadron spectrum with two flavors of staggered quarks | We present an update on the MILC Collaboration's light hadron spectrum calculation with two flavors of dynamical, staggered quarks. Results are presented for gauge couplings 5.30, 5.415, 5.50 and 5.60, with a range of quark masses for each value of the coupling. We present extrapolations of mN/mp ... | Staggered quarks; Hadron spectrum | 1998-04 |
