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 ... -
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 ... -
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 ... -
Multiphase coexistence with sequence fractionation in random block copolymers
(2012-01-16)Random binary block copolymers emerge from linking permanently and at random prepolymer blocks of two different chemical species A and B. The competitive interplay of conformational entropy, ... -
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 ... -
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 ... -
Orientational order and glassy states in networks of semiflexible polymers
(2011-02-01)Motivated by the structure of networks of cross-linked cytoskeletal biopolymers, the orientationally ordered phases in networks of randomly cross-linked semiflexible polymers are studied ... -
Aggregation and Gelation in Random Networks
(2010-06-23)In this thesis the formation, elasticity, and structure of randomly cross-linked networks is investigated analytically and with the help of computer simulations. In the first two chapters, ... -
Phase behaviour of random copolymers and crosslinked homopolymer blends
(2005-11-25)The phase behaviour of molten linear random block copolymers and of randomly crosslinked homopolymer blends is studied in the framework of statistical mechanics based on microscopic models.In ... -
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 ... -
Stationary Properties of Driven Granular Gases
(2005-03-18)We study driven granular gases in two dimensions. First we present systems of smooth particles between two vibrating walls. For these intrinsically inhomogeneous systems we measure all ... -
Free cooling of granular particles with rotational degrees of freedom
(2001-11-06)Aim of this theses is to elucidate the role of rotational degrees of freedom in a system of freely cooling granular particles. To gather more general aspects rough spherical particles and, as an example for non-spherical ... -
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 ...
