A semi-microscopic model of synaptic transmission and plasticity
(2000-08-28)A stochastic model of synaptic transmission has been designed on the basis of electro-physiological experiments. Monte Carlo simulations are performed which include presynaptic mechanisms ... -
Biomembranen an Grenzflächen und in synaptischer Geometrie
(2001-02-22)Inhomogeneous distributions of ion channels are ubiquitous in biological membranes and important for many biological functions. Therefore many theoretical models have been set up, which try ... -
Critical dynamics of gelling polymer solutions
(2005-08-29)This thesis addresses critical dynamics of randomly crosslinked polymeric liquids within semi-microscopic models. Therefore, the well known Rouse- and Zimm model are generalized to random ... -
Dense Granular Fluids and the Granular Glass Transition
(2011-11-17)Driven granular fluids at finite density are investigated theoretically and numerically for nontrivial correlations and for the formation of an dynamically arrested, amorphous, i.e., glassy ... -
Einfache Modelle für komplexe Biomembranen
(2003-10-22)Biomembranes are complex two-dimensional fluids consisting of proteins and lipids. In this work, simple molecular models are developed, applied and discussed to describe the thermodynamic ... -
Elastizität von vernetzten semiflexiblen Biopolymersystemen
(2015-06-29)In eukaryotic cells biopolymers such as actin filaments can arrange in various ways due to actin binding proteins, and for many cellular processes such biopolymers are of crucial importance. In this thesis, two different ... -
Energy dissipation and transport in polymeric switchable nanostructures via a new energy-conserving Monte-Carlo scheme
(2018-04-13)Polymers are materials that are widely used in industry. The advantages of polymers are their comparatively simple possibility of processing, e.g, injection moulding processes, 3D printers, and self-assembly. Polymers ... -
Entropy Production and Phase Transitions far from Equilibrium with Emphasis on Wet Granular Matter
(2008-11-14)This thesis investigates irreversible dynamics. It is shown analytically that the recent Fluctuation Theorem extends to relativistic dynamics. In the analytic consideration of non-relativistic ... -
Estimating Orientational Water Entropy at Protein Interfaces
(2012-02-09)The entropy of solvents significantly contributes to the stability of the native state of proteins. However, obtaining solvent entropies from molecular dynamics simulations remains a ... -
Friction and diffusive light transport in a granular medium
(2012-03-05)This thesis presents experimental research on the statics and dynamics of granular media. In the first part, it is shown that the surface roughness, and thence the interparticle friction ... -
Geometric structure and mechanical stability of disordered tetrahedra packings
(2013-12-18)In this study, the geometric structure of frictional, disordered tetrahedra packings is analysed in detail via X-ray Computed Tomography. The choice of the granulate is motivated by moving away from the "spherical cow" ... -
Grundzustandsstruktur ungeordneter Systeme und Dynamik von Optimierungsalgorithmen
(2005-12-12)Combinatorial optimization problems from Theoretical Computer Sciences and certain magnetic alloys (called spin glasses) both consist of particles or variables which are coupled by a large ... -
Impact of Complex Network Topology on Synchronization Dynamics
(2012-12-20)Synchrony is one of the most common dynamical states emerging on networks. The speed of convergence towards synchrony provides a fundamental collective time scale for synchronizing systems. Here we study the asymptotic ... -
Kinetics of Directed Self-Assembly of Block Copolymers via Continuum Models
(2019-02-22)The development of nanostructured materials relies on the advancement of our understanding of their properties and behavior at the molecular level. To leverage the potential of block-copolymers (BCP) as a cutting-edge ... -
Kinetics of structure formation in block copolymers
(2018-04-25)Block copolymers are amphiphilic macromolecules, which consist of multiple incompatible parts. Although block copolymers may differ in their microscopic interactions, their phase behaviors share many similarities. In ... -
Length scales in granular matter
(2013-04-24)Jammed packings of granular materials differ from thermal systems normally described by statistical mechanics. In recent years a statistical mechanics of static granular media has emerged by using the volume of the system ... -
Liquid Crystal Microswimmers - from single entities to collective dynamics
(2016-11-15)Recently, artificial self-propelled systems at low Reynolds numbers have gained a lot of attention. The main interest lies in mimicking well-studied systems, e.g. the active Brownian motion of bacteria, or in gaining deeper ... -
Low Temperature Phase of the m-component Spin Glass
(2011-09-15)We investigate the low temperature phase of a vector spin glass in the limit of large component numbers $m$ of the spins, where this model is expected to be replica symmetric. On a Bethe ... -
Microscopic models of energy dissipation by internal degrees of freedom in particle collisions
(2001-11-06)A microscopy model of energy dissipation in collisions of macroscopic bodies is investigated. Dissipation of translational energy is modelled by excitation of elastic vibrations of the ... -
Molecular dynamics of clathrin proteins at endocytic sites studied with evanescent-wave microscopy
(2004-10-04)Clathrin (consisting of a light chain and a heavy chain subunit) is a triskelion-shaped molecule that self-assembles into polyhedral lattices on cellular membranes. It has a pivotal role ...
