1 Friedrich, Frances; Walker, James A.Effects of parietal injury on covert orienting of visual attentionThe cognitive act of shifting attention from one place in the visual field to another can be accomplished covertly without muscular changes. The act can be viewed in terms of three internal mental operations: disengagement of attention from its current focus, moving attention to the target, and enga...Dominance, Cerebral; Attention; Extinction, Psychological1984-07
2 Vardeny, Zeev ValentineMechanism for photogeneration of charge carriers in polyacetyleneIn light of new experimental observations, a mechanism for the photogeneration of charge carriers in trans-polyacetylene is presented. By way of introduction, we discuss the qualitative changes in the picture of charged-soliton photogeneration that are expected due to the inclusion of electron corre...Photogeneration; Charge carriers; Photocarriers1984-07
3 Wu, Yong-ShiMultiparticle quantum mechanics obeying fractional statisticsWe obtain the rule governing many-body wave functions for particles obeying fractional statistics in two (space) dimensions. It generalizes and continuously interpolates the usual symmetrization and antisymmetrization. Quantum mechanics of more than two particles is discussed and some new features a...Multiparticle quantum mechanics; Fractional statistics1984-07
4 Vardeny, Zeev ValentinePhotoinduced absorption spectra in α-GeH and α-Si:HMeasurements of steady-state photoinduced absorption in α-Ge:H and α-Si:H were extended to cover the energy range from 0.25 to 1.9 eV. The subgap photoinduced-absorption bands in both materials are interpreted in terms of four kinds of optical transitions of photogenerated carriers from traps in ...Photoinduced absorption; in a-GeH; a-Si:H; Amorphous germanium; Amorphous silicon1984-07
