Gondolo, Paolo | Neutralino relic density including coannihilations | We evaluate the relic density of the lightest neutralino, the lightest supersymmetric particle, in the minimal supersymmetric extension of the standard model. For the first time, we include all coannihilation processes between neutralinos and charginos for any neutralino mass and composition. We u... | Neutralinos; Charginos; Higgsinos; Relic density; Coannihilations; Boltzmann equation | 1997-08 |

Vardeny, Zeev Valentine | Ring microlasers from conducting polymers | We demonstrate pulsed, photopumped multimode laser emission in the visible spectral range from cylindrical microcavities formed by conducting polymer thin films deposited around optical fibers. The laser is characterized by narrow emission lines (~1.5 cm-1), a well-defined excitation threshold, an... | Ring microlasers; Laser emission; Waveguided ring modes; Whispering gallery modes | 1997-08 |

Vardeny, Zeev Valentine | Spin and spectral signatures of polaron pairs in ∏-conjugated polymers | We have studied polaron pair photoexcitations in a variety of p-conjugated polymer films by photoinduced absorption (PA) and optically detected magnetic resonance (ODMR). Both luminescent and nonluminescent polymers have been studied. An exchange interaction between polarons broadens their magneti... | Spin signatures; spectral signatures; Photoinduced absorption; Photoexcitation | 1997-08 |
