Interactions Within and Between Cytoskeletal Filaments
(2023-05-26)Cellular mechanics are determined by the cytoskeleton which consists of three different kind of biopolymers – actin filaments, microtubules and intermediate filaments – which form an intricate network. Each filament type ... -
Rheology and Structure Formation in Complex Polymer Melts
(2019-04-17)Polymeric materials are ubiquitous in our modern lives. Their many applications in complex materials are accompanied by potentially huge benefits for technological advancement. These applications range from batteries, ... -
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 ... -
Study of active particles in heterogeneous media
(2018-09-07)In this thesis I present simulation-based studies of systems of self- propelled particles in heterogeneous media. I consider the interaction of particles with planar walls, single spherical obstacles or arrays of randomly ... -
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 ... -
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 ... -
Self-Organized Dynamics of Power Grids: Smart Grids, Fluctuations and Cascades
(2017-12-18)Climate change is one of the most pressing issues of our time and mitigating it requires a reduction of CO2 emissions. A big step towards achieving this goal is increasing the share of renewable energy sources, as the ... -
Real-time MRI and Model-based Reconstruction Techniques for Parameter Mapping of Spin-lattice Relaxation
(2017-09-05)Magnetic resonance imaging (MRI) is a non-invasive technique widely used for imaging of humans and animals. It came into existence based on several fundamental inventions made in the 1970s. Since then, MRI has evolved into ... -
Rheology of Weakly Attractive Soft Particles
(2016-12-14)We study the rheology of a soft particulate system with attractive interactions. Lees-Edwards boundary conditions are used to simulate a shear-controlled flow. Unlike repulsive systems, it is found that in systems with a ... -
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 ... -
Elasticity of basic structural element in anisotropic macromolecular networks
(2016-09-27)Semiflexible filaments are abundant in biological materials. From cells to the extracellular environment, these kind of filaments are found. They are important for many biological organizations and processes. The maintenance ... -
Rheology of frictional grains
(2016-08-19)This thesis deals with the description of flow and arrest of granular matter. Granular matter can undergo a rigidity transition — called jamming — that is mainly controlled by the applied stresses and the packing fraction ... -
The interplay between curvature and composition in binary mixture lipid bilayers
(2016-04-08)In this work we investigate, via computer simulations with an implicit-solvent coarse-grained model, the interplay between curvature and composition in self- assembled lipid structures comprised by two lipid species with ... -
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 ... -
Pattern Formation in Membranes with Quenched Disorder
(2015-01-23)The lateral heterogeneity in the plasma membrane of eukaryotic cells is an important factor for regulating biological functions. As opposed to plasma membranes, model membranes (either artificially prepared membranes, or ... -
Time-Symmetry Breaking in Turbulent Multi-Particle Dispersion
(2014-10-02)In fluid dynamics, the term turbulence usually describes a special state of a continuous medium in which many interacting degrees of freedom are excited. Turbulent flows therefore exhibit strong temporal and spatial ... -
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" ... -
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 ... -
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 ... -
