Vardeny, Zeev Valentine; Ehrenfreund, Eitan A. | Amplitude and phase modes in trans-polyacetylene: resonant Raman scattering and induced infrared activity | The resonant Raman scattering (RRS) from the three Ag modes of trans-polyacetylene and the charged-induced ir modes are analyzed with use of the amplitude- and phase-mode theories. It is shown that the observed phonon frequencies and the relative intensities of all modes obtained at various laser ex... | Induced infrared activity; Ag modes; Amplitude modes; Phase modes; Trans-polyacetylene | 1987-07 |

DeTar, Carleton | Hadronic spectrum of the quark plasma | We have carried out a numerical simulation in SU(3) lattice gauge theory with four flavors of low-mass staggered fermions at zero baryon-number density in the vicinity of the high-temperature phase transition on 6x 103 and 6x 102x20 lattices. Static screening masses (static susceptibilities) were m... | Hadronic matter; Quark plasma; Chiral symmetry; Phase transitions | 1987-07 |

Mattis, Daniel C. | Implications of infrared instability in a two-dimensional electron gas | We consider the tight-binding energy band in sq lattices and determine that in the half-filled case there exists an infrared instability in addition to the 2kF (nesting)-type instability. In view of the pseudo-two-dimensional band structure of La2-xBaxCu04 recently proposed by Jorgensen et al. and b... | Fermi surface; Bosonization | 1987-07 |
