 | Mishchenko, Eugene | Coulomb drag by small momentum transfer between quantum wires | We demonstrate that in a wide range of temperatures Coulomb drag between two weakly coupled quantum wires is dominated by processes with a small interwire momentum transfer. Such processes, not accounted for in the conventional Luttinger liquid theory, cause drag only because the electron dispersion... | Coulomb drag; Quantum wires; Luttinger liquid | 2003-09 |

 | Lupton, John Mark | Experimental evidence for exciton scaling effects in self-assembled molecular wires | Resonant Rayleigh scattering from self-assembled one-dimensional molecular J-aggregate wires reveals a distinct dependence of the exciton energy on the width of lateral extension. For the J aggregates used in this study, strong in-line dipole coupling leads to a delocalization of the exciton wave fu... | Exciton scaling effects; Molecular wires; J-aggregate wires; Quantum wires | 2004-12 |

 | Scarpulla, Michael | Fabrication of GaNxAs1-x quantum structures by focused ion beam patterning | A novel approach to the fabrication of GaNxAs1-x quantum dots and wires via ion beam patterning is presented. Photomodulated reflectance spectra confirm that N can be released from the As sublattice of an MBE-grown GaNxAs1-x film by amorphization through ion implantation followed by regrowth upon r... | Gallium arsenide; Quantum dots; Quantum wires; Thermal annealing | 2005 |

 | Mishchenko, Eugene | Generation of spin current by Coulomb drag | Coulomb drag between two quantum wires is exponentially sensitive to the mismatch of their electronic densities. The application of a magnetic field can compensate this mismatch for electrons of opposite spin directions in different wires. The resulting enhanced momentum transfer leads to the conv... | Spin current; Coulomb drag; Quantum wires | 2006-12 |

 | Mishchenko, Eugene | Pseudospin ferromagnetism in double-quantum-wire systems | We propose that a pseudospin ferromagnetic (i.e., interwire coherent) state can exist in a system of two parallel wires of finite width in the presence of a perpendicular magnetic field. This novel quantum many-body state appears when the interwire distance decreases below a certain critical value ... | Coulomb drag; Quantum wires | 2005-08 |
