Wu, Yong-Shi | Multisheet configuration space and fractional quantum statistics | We show that if one uses a multisheet configuration space for a system of identical particles, then fractional quantum statistics in two dimensions can be geometrically characterized as a topological quantum number for going from one sheet to the next. Furthermore, the spectrum of such a g-sheet s... | 1992-05 | |

Wu, Yong-Shi | Nonlinear Ŵ∞ current algebra in the SL(2,R)/U(1) coset model | We show that in the world-sheet SL(2,R)/U(l) coset model there exists a hidden nonlinear W∞ current algebra, which incorporates all higher-spin (s≥ 2) currents including the energy-momentum tensor. Our proof is based on a free-field realization of Woo in terms of two scalars, as well as an ele... | W-algebras; Coset model; World-sheet; String theory; Spacetime; Quantum currents | 1992-05 |

Vardeny, Zeev Valentine | Photoexcitation dynamics in polyacetylene probed by transient photoinduced resonant Raman scattering | We have measured photoexcitation dynamics in the picosecond time domain in fully trans and partially isomerized (CH)X and (CD)X films with different cis/trans content ratios, using the technique of transient photoinduced resonant Raman scattering. Following the distinctively different decay kineti... | Photoexcitation dynamics | 1992-05 |

DeTar, Carleton | QCD thermodynamics with two flavors at Nt=6 | The first results of numerical simulations of quantum chromodynamics on the Intel iPSC/860 parallel processor are presented. We performed calculations with two flavors of Kogut-Susskind quarks at Nt = 6 with masses of 0.15T and 0.075T (0.025 and 0.0125 in lattice units) in order to locate the crosso... | Kogut-Susskind quarks; Crossover temperature; Chiral symmetry; Polyakov loop; Phase transitions | 1992-05 |
