Study of Microinstabilities Using the Paraxial WKB Method Studie über Mikroinstabilitäten durch paraxialen WKB-Näherung
Author(s) :
Serbu , Monica
Description :
This thesis discusses a novel approach for solving the eigenvalue problem of plasma instabilities in the short wavelength limit. An asymptotic technique, the paraxial WKB, is employed to formulate the model, and the resulting equations obtained in the fluid limit are implemented numerically. This ne...

Quantenreflexion von Wellenpaketen an atomaren Potentialen Quantum Reflection of Wave-Packts at atomic Potentials
Author(s) :
Jurisch, Alexander
Description :
Es wird die Kinematik von atomaren Wellenpaketen untersucht, die im langreichweitigen Schwanz eines Atom-Oberflächen-Potentials kQuantenreflexion erfahren. Diese spielt auf dem hochaktuellen Gebiet der ultrakalten Atome eine wichtige Rolle, weil die Reflexionswahrscheinlichkeit an der Potentialschwe...

Quantum Information Processing with Atomic Ensembles and Light Quanteninformationsverarbeitung mit atomaren Ensembles und Licht
Author(s) :
Hammerer, Klemens
Description :
This thesis contributes to the theory of a light-matter quantum interface based on the Kerr-effect arising in the dispersive interaction of pulsed laser light with a spin-polarized atomic ensemble. The scattering process can be described on the basis of a simple, yet fully quantum mechanical model i...

Entanglement and Correlations in Cold Atomic Systems Verschränkung und Korrelationen in kalten atomaren Systemen
Author(s) :
Popp, Markus
Description :
This thesis is devoted to the theoretical characterization and generation of strongly correlated many-body states from the perspective of quantum information theory. We first study the entanglement properties of general many-body states and define a new measure for multipartite entanglement, the "Lo...

Quantum Entanglement: Theory and Applications Verschränktheit: Theorie und Anwendungen
Author(s) :
Schuch, Norbert
Description :
This thesis investigates questions related with the quantification, creation and
application of entanglement. We first show how the notion of entanglement is
modified by the presence of superselection rules. Next, we develop protocols
for the optimal generation of squeezing and entanglement from no...

Entanglement States in Ion Traps Verschränkte Zustände in Ionenfallen
Author(s) :
Deng, Xiaolong
Description :
This thesis is devoted to the theoretical study of strongly correlated quantum many-body states with trapped ions interacting
with lasers. A system of trapped ions under the action of off--resonant standing--waves can be used to simulate a variety of
quantum interacting models. Based on this idea we...

ParaGauss - A Parallel Implementation of the Density Functional Method: Symmetrized and Open-Shell variants of the TDDFT Method and Application to Optical Spectra of Adsorbed Metal Species ParaGauss - Eine Parallelisierte Implementierung der Dichte-Funktional-Methode: Symmetrisierung und Variante für Offenschalige Systeme der TDDFT Methode sowie Anwendungen auf Optische Spektren von Adsorbierten Metallspezies
Author(s) :
Bosko, Sergey
Description :
Time-dependent density functional theory (TDDFT) has been implemented in the parallel density functional code ParaGauss based on previously separate software. Achievements of the present work are the extension of the method to open-shell systems and the exploitation of symmetry. The TDDFT module has...

Molecular Dynamics Study of Solvent Reorganization Energies for Electron Transfer Processes in DNA-Related Systems Lösungsmittelbeitrag zur Reorganisationsenergie aus Moleküldynamiksimulationen sowie Anwendungen auf Elektron-Transferprozesse in DNA und verwandten Systemen
Author(s) :
Vladimirov, Egor
Description :
The solvent reorganization energy, a key parameter of electron transfer, was evaluated by force field based molecular dynamics simulations. First a computational methodology was established which demonstrated that accounting for electronic polarization by means of a polarizable force field reduces t...

Die Quantisierungsfunktion für attraktive, singuläre Potentialschwänze Quantization function for attractive, singular potential tails
Author(s) :
Raab, Patrick Nicholas
Description :
Die Wechselwirkung von Atomen und Molekülen untereinander wird durch Potentiale mit attraktiven, singulären Potentialschwänzen vermittelt. Die Bindungsenergien werden über eine einfache Quantisierungsregel mittels einer Quantisierungsfunktion bestimmt. Diese ist bei schwellennahen Zuständen durch de...

Highly doubly excited states of two-electron atoms: spectra, cross sections and localization properties Hoch-doppelt-angeregte Zustände in Zwei-Elektronen Atomen: Spektren, Wirkungsquerschnitte und Lokalisierungseigenschaften
Author(s) :
Eiglsperger, Johannes
Description :
In the present thesis, spectral properties of highly doubly excited states of two-electron atoms are studied. A configuration interaction approach is successfully applied to the computation of highly doubly excited states up to the tenth single ionization threshold with various values of the total a...
