Wu, Yong-Shi | Anyons on a torus: braid group, Aharonov-Bohm period, and numerical study | We present a careful construction of anyons on a torus starting with the braid-group analysis. The rules of Wen, Dagotto, and Fradkin for putting anyons on a torus are reproduced with some minor improvements. The existence of noncontractible loops leads to braid-group representations characterized n... | Braid group; Magnetic flux | 1991-05 |

Vardeny, Zeev Valentine | High-pressure effects on ultrafast-relaxation kinetics of excitons in polydiacetylene 4BCMU | Ultrafast-relaxation kinetics of the singlet excitons in polydiacetylene 4BCMU was measured at hydrostatic pressures up to 80 kbar, using the pump-probe photoinduced-absorption technique with 70-fs resolution at 2 eV and 5 ps in the spectral range 1.2-2.2 eV. The 100-fs decay component survives at... | Ultrafast-relaxation; Polydiacetylene 4BCMU; Pi-conjugated polymers; Quasi-1D excitations | 1991-05 |
