exponentially accurate error estimates of quasiclassical eigenvalues. II. several dimensions
(AIP Publishing, 2003-07)
We study the behavior of truncated Rayleigh-Schrodinger series for low-lying eigenvalues of the time-independent Schrodinger equation, in the semiclassical limit (h) over bar SE arrow0. In particular we prove that if the ...
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 ...
Pyramidal and toroidal water drops after impact on a solid surface
(Cambridge University Press, 2003-06)
Superhydrophobic surfaces generate very high contact angles as a result of their microstructure. The impact of a water drop on such a surface shows unusual features, such as total rebound at low impact speed. We report ...
NuTeV anomaly, neutrino mixing, and a heavy Higgs boson
(Amer Physical Soc, 2003-04-01)
Evidence of decoupled lattice distortion and ferroelectric polarization in the relaxor system PMN-xPT
(American Physical Society, 2003-12-30)
We report high q-resolution neutron scattering data on PMN-xPT single crystals with x=20% and 27%. No rhombohedral distortion occurs in the 20PT sample for temperatures as low as 50 K. On the other hand, the 27PT sample ...
Nonlinear current-induced forces in Si atomic wires
(American Physical Society, 2003-04)
We report first-principles calculations of current-induced forces in Si atomic wires as a function of bias and wire length. We find that these forces are strongly nonlinear as a function of bias due to the competition ...
Reaction-controlled diffusion: Monte Carlo simulations
(Amer Physical Soc, 2003-10-01)
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 ...
Scale invariance and dynamic phase transitions in diffusion-limited reactions
(Springer-Verlag Berlin, 2003-01-01)
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 ...
