Mattis, Daniel C. | Application of tridiagonalization to the many-body problem | The problem of a single magnetic, Wolff-model impurity in an otherwise ideal metallic host is investigated using the nonperturbative Lanczos method. Convergence is very rapid. The many-body ground-state energy is investigated and comparisons are made with Tomonaga operator theory and other weak-coup... | Lattice; Electrons; Interaction; Ground-state energy; Tridiagonalization; Magnetic impurity; Nonmagnetic metals | 1983 |

Ailion, David Charles | Floating of the modulation wave and phase pinning in incommensurate Rb2ZnBr4 | Nuclear-magnetic-resonance measurements in incommensurate Rb2ZnBr4 show the existence of regions where the modulation wave is floating. The floating regions coexist with other regions where the modulation wave is static. Impurity phase pinning and a roughening of the modulation wave at higher temper... | Floating; Incommensurate phase; Phason mode; Lattices | 1983 |

Vardeny, Zeev Valentine | Photoinduced IR active vibrations in trans-(CD)x: a three-mode system | In a recent Letter Blanchet et al.? have extended photoinduced absorption measurements of frYms-polyacetylene to lower energy than obtained before 2 for both isotopes, (CH)x and (CD)X. While in (CE)X three strong ir-active vibrations (IRAV) are photoinduced, only two IRAV were observed in (CD)X, at... | Photoinduced absorption; IR active vibrations | 1983 |

Vardeny, Zeev Valentine | Picosecond trapping of photocarriers in amorphous silicon | Trapping of photoexcited carriers in the picosecond and subnanosecond time domains was studied by measuring the decay of photoinduced absorption (PA) in a-Si, a-Si:F, a-Si:H, and a-Si:H:F. We found that when the midgap density of states decreases, both the trapping time and its temperature dependenc... | Photocarriers; Amorphous silicon; Picosecond trapping; Photoinduced absorption | 1983 |
