1. Multiconfigurational perturbation theory
Abstract : The aim of the thesis is to analyze a method which describes the electron correlation in atoms and molecules. The method is based on Rayleigh-Schrödinger perturbation theory with a partitioning of the Hamiltonian into a fairly simple zeroth-order operator and a perturbation operator. READ MORE

2. Topics in perturbation theory : From IBP identities to integrands
Abstract : In this thesis we present different topics in perturbation theory. We start by introducing the method of integration by parts identities, which reduces a generic Feynman integral to a linear combination of a finite basis of master integrals. READ MORE

3. Fundamental Investigations of Supercritical Fluid Chromatography
Abstract : This thesis aims at a deeper understanding of Supercritical FluidChromatography (SFC). Although preparative SFC has started to replace Liquid Chromatography (LC) in the pharmaceutical industry - because of its advantages in speed and its less environmental impact - fundamental understanding is still lacking.

4. Adsorption Isotherm Parameter Estimation in Nonlinear Liquid Chromatography
Abstract : This thesis concerns the development and validation of methods for the industrially important area of adsorption isotherm parameter estimation in preparative, nonlinear high performance liquid chromatography (HPLC). Preparative chromatography is a powerful separation method to get pure compounds from more or less complex liquid mixtures, e.g. READ MORE
