In this talk, we will introduce a novel overlapping domain decomposition splitting algorithm based on a Crank--Nisolson method is developed for the stochastic NLS equation driven by a multiplicative n...
WAVELET DECOMPOSITION OF HYPERSPECTRAL REFLECTANCE DATA FOR QUANTIFYING PHOTOSYNTHETIC PIGMENT CONCENTRATIONS IN VEGETATION
Remote Sensing Vegetation Hyper spectral Analytical Experiment
2015/7/29
The dynamics of pigment concentrations are related to vegetation photosynthetic potential and hence primary production, nutrient
status, stress physiology and plant-environment interactions. Therefo...
A Bloch decomposition based split-step pseudo spectral method for quantum dynamics with periodic potentials
Schrodinger equation Bloch decomposition time-splitting spectral method semiclassical asymptotics lattice potential
2012/5/24
We present a new numerical method for accurate computations of solutions to (linear) one dimensional Schr\"odinger equations with periodic potentials. This is a prominent model in solid state physics ...
Superluminal Spin-1/2 Particles are Left-Handed: From the Gordon Decomposition to the Suppression of Right-Handed States
Superluminal Spin-1/2 Particles Gordon Decomposition Suppression of Right-Handed States High Energy Physics Phenomenology
2012/5/17
Superluminal spin-1/2 particles are analyzed under the assumption that the equation of motion is compatible with Lorentz invariance (tachyonic particles). It is found that tachyonic spin-1/2 particles...

Linearly independent pure-state decomposition and quantum state discrimination
Linearly independent decomposition quantum discrimination
2010/11/8
We put the pure-state decomposition mathematical property of a mixed state to a physical test. We begin by characterizing all the possible decompositions of a rank-two mixed state by means of the comp...

2010/7/5
Fischer-Tropsch synthesis is a part of Gas-to Liquids (GTL), Biomass-to-Liquids (BTL) and Coal to Liquids (CTL) technologies, which produce alternatives clean fuels from natural gas, biomass and coal....
The propagator for the step potential using the path decomposition expansion
propagator step potential path decomposition expansion
2010/4/9
We present a direct path integral derivation of the propagator in the presence of a step potential. The derivation makes use of the Path Decomposition Expansion (PDX), and also of the definition of th...
