Mishchenko, Eugene | Optical conductivity of a two-dimensional electron liquid with spin-orbit interaction | The interplay of electron-electron interactions and spin-orbit coupling leads to a new contribution to the homogeneous optical conductivity of the electron liquid. The latter is known to be insensitive to many-body effects for a conventional electron system with parabolic dispersion. The parabolic... | Optical conductivity; Electron liquid; Spin-orbit coupling | 2006-08 |

Mishchenko, Eugene | Zero-bias anomaly in two-dimensional electron layers and multiwall nanotubes | The zero-bias anomaly in the dependence of the tunneling density of states n (e) on the energy e of the tunneling particle for two- and one-dimensional multilayered structures is studied. We show that for a ballistic two-dimensional (2D) system the first-order interaction correction to density of s... | Spin-orbit coupling; Coulomb interaction | 2002-05 |

Wu, Yong-Shi; Raikh, Mikhail E. | Role of spin-orbit coupling in the metal-insulator transition in two-dimensional systems | We propose an experiment, which would allow us to pinpoint the role of spin-orbit coupling in the metal-nonmetal transition observed in a number of two-dimensional systems at low densities. Namely, we demonstrate that in a parallel magnetic field the interplay between the spin-orbit coupling and the... | Spin-orbit coupling; Metal-insulator transitions | 2000-04 |

Mishchenko, Eugene | Transport equations for a two-dimensional electron gas with spin-orbit interaction | The transport equations for a two-dimensional electron gas with spin-orbit interaction are presented. The distribution function is a 232-matrix in the spin space. Particle and energy conservation laws determine the expressions for the electric current and the energy flow. The derived transport equ... | Spin-orbit coupling | 2003-07 |

Mishchenko, Eugene | Breached superfluidity via p-wave coupling | Anisotropic pairing between fermion species with different Fermi momenta opens two-dimensional areas of gapless excitations, thus producing a spatially homogeneous state with coexisting superfluid and normal fluids. This breached pairing state is stable and robust for arbitrarily small mismatch and ... | Spin-orbit coupling; Gapless excitations; Cooper instability | 2005-03 |

Mishchenko, Eugene; Raikh, Mikhail E. | Tunneling between two-dimensional electron layers with correlated disorder: anomalous sensitivity to spin-orbit coupling | Tunneling between two-dimensional electron layers with mutually correlated disorder potentials is studied theoretically. Due to this correlation, the diffusive eigenstates in different layers are almost orthogonal to each other. As a result, a peak in the tunnel I-V characteristics shifts towards s... | Spin-orbit coupling | 2006-11 |

Mishchenko, Eugene | Small-angle impurity scattering and the spin Hall conductivity in two-dimensional semiconductor systems | An arbitrarily small concentration of impurities can affect the spin Hall conductivity in a two-dimensional semiconductor system. We develop a Boltzmann-like equation that can be used for impurity scattering with an arbitrary angular dependence, and for an arbitrary angular dependence of the spin-o... | Spin Hall conductivity; Impurity scattering; Spin-orbit coupling | 2006-02 |

Armentrout, Peter B. | Reactions of Ta+, W+, and Pt+ with H2, D2, and HD: effect of lanthanide contraction and spin-orbit interactions on reactivity and thermochemistry | There have been extensive experimental studies of the reactions of atomic first-row and second-row transition metal cations with dihydrogen and its isotopic analogues in our group. For third-row transition metal cations, however, only La+ and Lu+ systems have been studied experimentally although t... | Lanthanide contraction; Spin-Orbit interactions; Reactivity | 2002 |

Mishchenko, Eugene | Polarized electric current in semiclassical transport with spin-orbit interaction | Semiclassical solutions of two-dimensional Schrödinger equation with spin-orbit interaction and smooth potential are considered. In the leading order, spin polarization is in-plane and follows the evolution of the electron momentum for a given subband. Out-of-plane spin polarization appears as a ... | Spin-polarized current; Sharvin conductance; Spin-orbit coupling | 2006-10 |

Mishchenko, Eugene | Spin current and polarization in impure two-dimensional electron systems with spin-orbit coupling | We derive the transport equations for two-dimensional electron systems with Rashba spin-orbit interaction and short-range spin-independent disorder. In the limit of slow spatial variations, we obtain coupled diffusion equations for the electron density and spin.
