Chaotic transport in low-dimensional superlattices
(American Physical Society, 2003-02)
We predict that in arrays of quantum dots (0D superlattice) and arrays of one-dimensional quantum wires (1D superlattice) chaotic transport should be observed in the presence of an ac field and for a wide range of physical ...
NuTeV anomaly, neutrino mixing, and a heavy Higgs boson
(Amer Physical Soc, 2003-04-01)
inertia-induced breakup of highly viscous drops subjected to simple shear
(AIP Publishing, 2003-05)
We investigate the inertia-driven breakup of viscous drops suspended in a less viscous liquid under simple shear. For Stokes flow, it is known that there is a critical value of the viscosity ratio, beyond which breakup ...
Lo numerico y la Sustentabilidad
(Ethics in Science and Environmental Politics, 2003)
El uso sustentable del planeta se basa en el presupuesto de que la humanidad puede mantener las condiciones adecuadas para habitar el planeta indefinidamente. No hay evidencia robusta que apoye o niegue _sto y la evidencia ...
Transfer function approach to output specification in certain linear distributed parameter systems
(American Institute of Mathematical Sciences, 2003)
We carry out error estimation of a class of immersed finite element (IFE) methods for elliptic interface problems with both perfect and imperfect interface jump conditions. A key feature of these methods is that their ...
Effects of geometry and doping on the operation of molecular transistors
(AIP Publishing, 2003-03)
We report first-principles calculations of current versus gate voltage characteristics of a molecular transistor with a phenyldithiolate molecule as active element. We show that (i) when the molecule is placed in proximity ...
Quanta. Vol. 4, Issue 2 (October 2003)
(Virginia Tech Physics Department, 2003-10)
A semi-annual newsletter for the faculty, staff, students, alumni & friends of the Virginia Tech Physics Department.
Fluorinert as a pressure-transmitting medium for high-pressure diffraction studies
(AIP Publishing, 2003-10)
Fluorinert is a liquid pressure-transmitting medium that is widely used in high-pressure diffraction work. A systematic study of five different fluorinerts was carried out using single-crystal x-ray diffraction in a ...
large eddy simulation of turbulent channel flows by the rational large eddy simulation model
(AIP Publishing, 2003-10)
The rational large eddy simulation (RLES) model is applied to turbulent channel flows. This approximate deconvolution model is based on a rational (subdiagonal Pade) approximation of the Fourier transform of the Gaussian ...
Relevance of space anisotropy in the critical behavior of m-axial Lifshitz points
(American Physical Society, 2003-12)
The critical behavior of d-dimensional systems with n-component order parameter phi is studied at an m-axial Lifshitz point where a wave-vector instability occurs in an m-dimensional subspace R-m (m>1). Field theoretic ...
