HUANG, ZH; WEIMER, M.; Allen, Roland E. (American Physical Society, 1993)The tunneling of electrons from a semiconductor surface to a metal tip, across a vacuum gap, is influenced by two image interactions: an attractive image potential in the vacuum region, which lowers the apparent tunneling ...

Mondragon, Antonio Richard (2009-05-15)Observations from the 1930s until the present have established the existence of dark matter with an abundance that is much larger than that of luminous matter. Because none of the known particles of nature have the correct ...

Zhou, Xiang; Lin, Zhibin; Jiang, Chenwei; Gao, Meng; Allen, Roland E. (American Physical Society, 2010)For molecules and materials responding to femtosecond-scale optical laser pulses, we predict maximum relative excitation of a Raman-active vibrational mode with period T when the pulse has a full-width-at-halfmaximum ...
-
Yokoo, Seiichiro (2009-05-15)Physics in the year 2006 is tightly constrained by experiment, observation, and mathematical consistency. The Standard Model provides a remarkably precise de- scription of particle physics, and general relativity is quite ...

Shi, Jian-Hui (Texas A&M University. Libraries, 1993)In this thesis, I show how the basic solid-state NMR techniques can be used to study the local electronic structures of II-VI and III-V semiconductor alloys on an atomic scale. We have focused our studies on a few high ...
-
Xu, Guanglang (2017-12-13)The light scattering properties of some components in the atmosphere and ocean are of particular interests for their relevant applications in remote sensing and climate studies. In this dissertation, numerical studies are ...

Torralva, B.; Niehaus, TA; Elstner, M.; Suhai, S.; Frauenheim, T.; Allen, Roland E. (American Physical Society, 2001)In this paper we introduce a method for realistic simulations of nonadiabatic processes, including the interaction of light with matter. Calculations of the response Of C(60) and carbon chains to laser pulses demonstrate ...
-
Graves, JS; Allen, Roland E. (American Physical Society, 1998)Motivated by recent experiments, we have performed simulations which show in detail how the electrons and ions in GaAs respond to fast intense laser pulses (with durations of order 100 fs and intensities of order 1-10 ...
-
Huang, Xin (2013-08-01)An accurate and generalized global retrieval algorithm from satellite observations is a prerequisite to understand the radiative effect of atmospheric aerosols on the climate system. Current operational aerosol retrieval ...

KENNER, VE; Allen, Roland E.; SASLOW, WM. (American Physical Society, 1973)
-
Dumitrica, T.; Graves, JS; Allen, Roland E. (American Physical Society, 1998)Using a new formalism that modifies a tight-binding Hamiltonian to include interaction with a time-dependent electromagnetic field, we have obtained an analytical expression for the second-order susceptibility. This ...
