 | Vardeny, Zeev Valentine | Absorption-detected magnetic-resonance studies of photoexcitations in conjugated-polymer/C60 composites | Photoexcitations in poly[2-methoxy-5-(2'-ethyl-hexyloxy -p-phenylene vinylene] (MEH-PPV) and composites of MEH-PPV and C60 (MEH-PPV/C60) were studied by photoinduced absorption and absorptiondetected magnetic-resonance spectroscopies. We report direct evidence that the prominent triplet photoexci... | Photoexcitations; Conjugated-polymer/C60 composites; Triplet photoexcitations | 1996-02 |

 | Mishchenko, Eugene | Electronic Raman scattering in a magnetic field | Raman scattering in a magnetic field is proposed as a possible method to solve the problem of whether the light scattering in high-Tc superconductors comes from conduction electrons or not. The electronic Raman light scattering in a magnetic field is studied theoretically. The semiclassical approa... | Raman scattering | 1996-01 |

 | Wu, Yong-Shi | Hidden massive Dirac fermions in effective field theory for integral quantum Hall transitions | Integral quantum Hall plateau transitions in a planar lattice system due to gap collapse can be described by an effective field theory with Dirac fermions. We discuss how to reproduce the correct integral values for the Hall conductance sxy before and after the plateau transition, which are dictat... | Dirac fermions; Vorticities; Edge states; Hall conductance | 1996-08 |

 | Wu, Yong-Shi | Mutual-exclusion statistics in exactly solvable models in one and higher dimensions at low temperatures | We study statistical characterization of the many-body states in exactly solvable models with internal degrees of freedom. The models under consideration include the isotropic and anisotropic Heisenberg spin chains, the Hubbard chain, and a model in higher dimensions which exhibits the Mott metal-in... | Exclusion statistics; Exclusons; Hubbard chain | 1996-08 |

 | Vardeny, Zeev Valentine | Optically-detected magnetic-resonance study of triplet state dynamics in C70 | We present studies of fluorescence, phosphorescence, photoinduced absorption, and their respective optically detected magnetic resonance of C70 molecules dispersed in polystyrene glasses. Two distinct triplet excitons are identified with principle zero-field splitting parameters (D≈0.0089 and 0.0... | Ttriplet state dynamics; C70; Polystyrene glasses | 1996-03 |

 | Wu, Yong-Shi | Quantum group, Bethe ansatz equations, and Bloch wave functions in magnetic fields | The wave functions for a two-dimensional Bloch electron in uniform magnetic fields at the mid-band points are studied by exploiting a connection to the quantum group Uq(sl2): A linear combination of its generators gives the Hamiltonian. We apply both analytic and numerical methods to obtain and an... | Bloch electron | 1996-04 |
