Active turbulence in microswimmer suspensions -- the role of active hydrodynamic stress and volume exclusion
Kai Qi, Elmar Westphal, Gerhard Gompper +1
Microswimmers exhibit an intriguing, highly-dynamic collective motion with large-scale swirling and streaming patterns, denoted as active turbulence -- reminiscent of classical hig…
Enhanced rotational motion of spherical squirmer in polymer solutions
Kai Qi, Elmar Westphal, Gerhard Gompper +1
The rotational diffusive motion of a self-propelled, attractive spherical colloid immersed in a solution of self-avoiding polymers is studied by mesoscale hydrodynamic simulations.…
Influence of Bonded Interactions on Structural Phases of Flexible Polymers
Kai Qi, Benjamin Liewehr, Tomas Koci +3
We introduce a novel coarse-grained bead-spring model for flexible polymers to systematically examine the effects of an adjusted bonded potential on the formation and stability of…
Clustering of microswimmers: Interplay of shape and hydrodynamics
Mario Theers, Elmar Westphal, Kai Qi +2
The spatiotemporal dynamics in systems of active self-propelled particles is controlled by the propulsion mechanism in combination with various direct interactions, such as steric…
Classification of Phase Transitions by Microcanonical Inflection-Point Analysis
Kai Qi, Michael Bachmann
By means of the principle of minimal sensitivity we generalize the microcanonical inflection-point analysis method by probing derivatives of the microcanonical entropy for signals…
Autocorrelation study of the Θ transition for a coarse-grained polymer model
Kai Qi, Michael Bachmann
By means of Metropolis Monte Carlo simulations of a coarse-grained model for flexible polymers, we investigate how the integrated autocorrelation times of different energetic and s…
