A molecular simulation analysis of producing monatomic carbon chains by stretching ultranarrow graphene nanoribbons
molecular simulation analysis monatomic carbon chains ultranarrow graphene nanoribbons Computational Physics
2012/4/20
Atomistic simulations were utilized to develop fundamental insights regarding the elongation process starting from ultranarrow graphene nanoribbons (GNRs) and resulting in monatomic carbon chains (MAC...
First-principles Analysis of Photo-current in Graphene PN Junctions
First-principles Analysis Photo-current Graphene PN Junctions
2012/2/29
We report a first principles investigation of photocurrent generation by graphene PN junctions. The junctions are formed by either chemically doping with nitrogen and boron atoms, or by controlling ga...

Software architectures (event data models, frameworks and databases), Data processing methods, Gamma detectors
2011/8/31
GELATIO is a new software framework for advanced data analysis and digital signal processing developed for the GERDA neutrinoless double beta decay experiment. The framework is tailored to handle the ...
An application of the variational analysis to calculate the meson spectral functions
application of the variational analysis calculate the meson spectral functions
2011/1/13
We present a new method to calculate meson spectral functions (SPFs) on the lattice based on
a variational method. Because, on a finite volume lattice, the meson SPFs have discrete spectra
only, a s...
Genetic algorithms and the analysis of SnIa data
Genetic algorithms analysis of SnIa data
2010/12/21
The Genetic Algorithm is a heuristic that can be used to produce model independent solutions to an optimization problem, thus making it ideal for use in cosmology and more specifically in the analysis...
Error probability analysis in quantum tomography: a tool for evaluating experiments
Error probability analysis quantum tomography: evaluating experiments
2010/10/19
We expand the scope of the statistical notion of error probability, i.e., how often large deviations are observed in an experiment, in order to make it directly applicable to quantum tomography. We ve...
