Tagged-particle dynamics in confined colloidal liquids
Gerhard Jung, Lukas Schrack, Thomas Franosch
We present numerical results for the tagged-particle dynamics by solving the mode-coupling theory in confined geometry for colloidal liquids (cMCT). We show that neither the micros…
Tagged-particle motion in quasi-confined colloidal hard-sphere liquids
Lukas Schrack, Charlotte F. Petersen, Michele Caraglio +2
We investigate the tagged-particle motion in a strongly interacting quasi-confined liquid using periodic boundary conditions along the confining direction. Within a mode-coupling t…
Mode-coupling theory of the glass transition for colloidal liquids in slit geometry
Lukas Schrack, Thomas Franosch
We provide a detailed derivation of the mode-coupling equations for a colloidal liquid confined by two parallel smooth walls. We introduce irreducible memory kernels for the differ…
An improved integration scheme for Mode-coupling-theory equations
Michele Caraglio, Lukas Schrack, Gerhard Jung +1
Within the mode-coupling theory (MCT) of the glass transition, we reconsider the numerical schemes to evaluate the MCT functional. Here we propose nonuniform discretizations of the…
Dynamical properties of densely packed confined hard-sphere fluids
Gerhard Jung, Michele Caraglio, Lukas Schrack +1
Numerical solutions of the mode-coupling theory (MCT) equations for a hard-sphere fluid confined between two parallel hard walls are elaborated. The governing equations feature mul…
Dynamic properties of quasi-confined colloidal hard-sphere liquids near the glass transition
Lukas Schrack, Charlotte F. Petersen, Gerhard Jung +2
The complex behavior of confined fluids arising due to a competition between layering and local packing can be disentangled by considering quasi-confined liquids, where periodic bo…
Persistent anti-correlations in Brownian dynamics simulations of dense colloidal suspensions revealed by noise suppression
Suvendu Mandal, Lukas Schrack, Hartmut Löwen +2
Transport properties of a hard-sphere colloidal fluid are investigated by Brownian dynamics simulations. We implement a novel algorithm for the time-dependent velocity-autocorrelat…
Static properties of quasi-confined hard-sphere fluids
Charlotte F. Petersen, Lukas Schrack, Thomas Franosch
Confined fluids display complex behavior due to layering and local packing. Here, we disentangle these effects by confining a hard-sphere fluid to the surface of a cylinder, such t…
Anti-margination of microparticles and platelets in the vicinity of branching vessels
C. Bächer, A. Kihm, L. Schrack +4
We investigate the margination of microparticles/platelets in blood flow through complex geometries typical for in vivo vessel networks: a vessel confluence and a bifurcation. Usin…
Clustering of microscopic particles in constricted blood flow
Christian Bächer, Lukas Schrack, Stephan Gekle
A mixed suspension of red blood cells (RBCs) and microparticles flows through a cylindrical channel with a constriction mimicking a stenosed blood vessel. Our three-dimensional Lat…
