The Exact Wavefunction Factorization of a Vibronic Coupling System

open access: yes, 2013
We investigate the exact wavefunction as a single product of electronic and nuclear wavefunction for a model conical intersection system. Exact factorized spiky poten-tials and nodeless nuclear wavefunctions are found.

Surface Water Body Detection in High-Resolution TerraSAR-X Data using Active Contour Models [PDF]

open access: yes, 2010
This paper presents the application of two different active contour models for the segmentation of high-resolution TerraSAR-X data. Both methods facilitate the detection of land-water-boundaries in semi-automated procedures and can be used to delineate ...

Dynamics of Green AuNP Formation and Their Application in Core-Shell Nanostructures [PDF]

open access: yes, 2011
The formation of gold nanoparticles in our optimized synthesis is achieved through reduction of tetrachloroauric acid in 2 - (N - morpholino)ethanesulphonic acid (MES) buffered glucose and stabilization by starch at room temperature.

Optically tailored magnetic potentials for ultracold atoms based on superconducting vortices

open access: yes, 2019
Atom chips are micro-fabricated devices which create versatile magnetic poten- tials for trapping, cooling and controlling ensembles of ultra-cold atoms. Ad- vancing from the typical atom chips, currents from superconducting vortices are used to trap and
