Tropical-cyclone evolution in a minimal axisymmetric model

Jul 25th, 2011

Diese Arbeit untersucht mithilfe eines axisymmetrischen numerischen Modells die Prozesse, die zur Intensivierung tropischer Zyklone führen. Das Modell ist hydrostatisch, die Mo-dellgleichungen sind in Sigmakoordinaten auf einer f-Ebene formulie

Microscopic Calabi-Yau Black Holes in String Theory

Jul 22nd, 2011

In this thesis we study microscopic aspects of Calabi-Yau black holes in string theory.We compute the absorption cross-section of the space-time massless scalars by the world-volumeof D2-branes, wrapped on the S2 of an AdS_2 x S^2 x CY_3 geom

The XMM-BCS galaxy cluster survey

Molecular dynamics simulations of protein-protein interactions and THz driving of molecular rotors on gold

Jul 19th, 2011

The scope of this work is to gain insight and a deeper understanding of exploring and controlling molecular devices like proteins and rotors by fine tuned manipulation via mechanical or electrical energies.I focus on three main topics.First,

Gauge/gravity duality

Jul 14th, 2011

In this dissertation we use gauge/gravity duality to investigate various phenomena of strongly coupled field theories. Of special interest are quantum phase transitions,quantum critical points, transport phenomena of charges and the thermaliza

Femtosekundenspektroskopie an o-substituierten Nitrobenzolen - von Modellen zu photolabilen Schutzgruppen

Jul 13th, 2011

In this thesis ultrafast processes occuring in photolabile protecting groups of the ortho-nitrobenzyl type have been studied. These protecting groups enable the spatially and temporarily defined release of chemically or biologically active mol

Development of an optically synchronized seed source for a high-power few-cycle OPCPA system

Jul 7th, 2011

The scheme of short-pulse pumped optical parametric chirped-pulse amplification (OPCPA) offers a promising route towards a completely new regime of ultra-high power few-cycle pulse generation, which reaches well beyond the limits of the convent

Biotechnological applications of thermophoresis

Jul 4th, 2011

For over 150 years it is known that particles in a temperature gradient conduct a directed movement. This is called the Soret effect or thermophoresis. Still the underlying physical principles of thermophoresis in aqueous solutions are not tot

Quasiparticles in Leptogenesis

Jun 29th, 2011

We analyse the effects of thermal quasiparticles in leptogenesis using hard-thermal-loop-resummed propagators in the imaginary time formalism of thermal field theory. We perform our analysis in a leptogenesis toy model with three right-handed h
