Mattis, Daniel C. | Dynamic properties of a nonsuperfluid Bose liquid in the random-phase approximation | The dynamic structure factor S(k,w) of a nonideal Bose liquid is calculated within the random-phase approximation and compared with neutron scattering data by Cowley and Woods for liquid helium in the temperature range Tλ<T≤4.2°K, with the conclusion that the model is wholly inadequate. A low-f... | Bose liquid; Random-phase approximation; Overdamping | 1974-11 |

Mattis, Daniel C. | Effect of band structure on ferromagnetism* | We extend Nagaoka's study of the ferromagnetism of nearly half-filled bands in the infinite-repulsion limit of the Hubbard model by including next-nearest-neighbor tight-binding overlap matrix elements K2. Particles can now get past one another, even in one dimension. We find corroboration of Nagaok... | Eigenstates; Spin waves | 1974-08 |

Ailion, David Charles | Effect of the translational diffusion mechanism on the low-field NMR spin-lattice relaxation time in the rotating reference frame: calculation of order parameter | The effect of the translational-diffusion mechanism on the low-field NMR spin-lattice relaxation time in the rotating reference frame is calculated for simple cubic, body-centered cubic, and face-centered cubic lattices. The results of these calculations suggest a new method for determining the pref... | NMR; Nuclear magnetic resonance; Lattices; Relaxation time | 1968 |

Normann, Richard A. | Effects of background illumination on the photoresponses of red and green cones | 1. The photoresponses of light- and dark-adapted red and green cone photoreceptors were recorded intracellularly in the retina of the turtle, Pseduemys scripta elegans. Background illumination produced similar effects on both types of cones. 2. In response to the onset of a prolonged, steady backgro... | Turtles; Adaptation, Ocular; Retina; Signal Transmission | 1979 |

Mattis, Daniel C. | Effects of orbital degeneracy on a magnetic impurity in a nonmagnetic metal | We study the Green's-function equations for a version of the two-orbital Anderson model of a magnetic impurity, in an approximation scheme that displays the logarithmic anomalies and enables the Kondo temperature Tĸ to be calculated as a function of the parameters. The nature of the solutions is ex... | Orbital degeneracy; Magnetic impurities; Nonmagnetic metal; Kondo temperature; Anomalous resonances | 1969-02 |

Lindstrom, Gary E. | Efficiency in nondeterministic control through non-forgetful backtracking | Nondeterministic (ND) control has long been used to express elegant solutions to complex search problems. Programs using ND control can be executed on conventional machines through a systematic examination of trial execution paths. Among the many approaches to the enumeration of these paths is backt... | Nondeterministic control; Non-forgetful backtracking; Search problems | 1977 |

Mattis, Daniel C. | Eigenstates of excitons near a surface | The exact eigenstates and energies of an electron and a hole of equal effective masses, with an attractive δ-function interaction and hard-wall repulsion at the surfaces of a solid, are classified and obtained explicitly for a solid of arbitrary thickness. Both bound and scattering states of the e... | Eigenstates; Frenkel excitons | 1978-10 |

Miller, Joel Steven; Epstein, Arthur J. | Elastic properties of (N(CH3)3H) (I) (TCNQ) | We present the results of a study of the temperature dependence of the Young's modulus and internal friction of (N(CH3 )3H)(I)(TCNQ). The Young's modulus was measured in a direction parallel to the TCNQ (tetracyanoquinodimethane) stacking axis using a vibrating reed technique. The results confirmed ... | Metal-like, Conductivity, Magnetic | 1979 |

Stringfellow, Gerald B. | Electron mobility in AlxGa1-xAs | he electron mobility in AlxGa1-xAs grown by several techniques has been studied to determine whether VPE layers are more highly compensated than comparable LPE layers. The techniques used to grow layers included (1) organometallic VPE using Al(CH3)3, AsH3, and Ga(C2H5)3 or Ga(CH3)3, (2) ''hybrid'' o... | Alloys; Organometallics | 1979-06 |

Mattis, Daniel C. | Electron states in random alloys with short-range order | We present an accurate and economical iterative method of calculating the energy levels of a disordered or partly ordered random alloy. Results presented for one- and three-dimensional simple cubic lattices compare favorably with exact calculations. We also present the systematic effects of partia... | Random alloys; Density of state | 1977-04 |
