Geometry-Induced Transport of Self-Aligning Chiral Bristlebots
Timo Wagner, Michael Himpel, Thomas Ihle +1
Active matter systems characterized by the interplay of chirality and self-alignment offer a rich landscape for non-equilibrium collective behaviors and the development of autonomo…
Dynamics of Aligning Active Matter: Mapping to a Schrödinger Equation and Exact Diagonalization
Tara Steinhöfel, Horst-Holger Boltz, Thomas Ihle
There has been recent interest in the relaxational modes of small-scale fully connected systems of aligning self-propelled particles (Spera et al., Phys. Rev. Lett. {\bf 132}: 0783…
Spectral insights into active matter: Exceptional Points and the Mathieu equation
Horst-Holger Boltz, Thomas Ihle
We show that recent numerical findings of universal scaling relations in systems of noisy, aligning self-propelled particles by Kürsten [Kürsten, arXiv:2402.18711v2 [cond-mat.soft]…
Reduced density fluctuations via anti-aligning in active matter
Horst-Holger Boltz, Thomas Ihle
We highlight the importance of long-range correlations in active matter systems of self-propelling particles even in the absence of global order or steric interactions by demonstra…
Comment on "Steady-state distributions and nonsteady dynamics in nonequilibrium systems"
Horst-Holger Boltz, Thomas Ihle
We comment on a work by T. Liverpool (Phys. Rev. E 101 (2020)). We show that a theorem stated in that work is not correct. While this is inconsequential to the bulk of the work (an…
Asymptotically exact scattering theory of the Kuramoto-Vicsek model
Thomas Ihle, Horst-Holger Boltz, Rüdiger Kürsten +1
We consider the Kuramoto-Vicsek model of self-propelled particles with velocity-alignment interactions. Starting from the exact -particle Liouville equation, a kinetic equation…
Quantitative spectroscopy of single molecule interaction times
Horst-Holger Boltz, Alexei Sirbu, Nina Stelzer +3
Single molecule fluorescence tracking provides information at nm-scale and ms-temporal resolution about the dynamics and interaction of individual molecules in a biological environ…
Fluctuation Distributions of Energy Minima in Complex Landscapes
Horst-Holger Boltz, Jorge Kurchan, Andrea J. Liu
We discuss the properties of the distributions of energies of minima obtained by gradient descent in complex energy landscapes. We find strikingly similar phenomenology across seve…
Elastic capsules at liquid-liquid interfaces
Jonas Hegemann, Horst-Holger Boltz, Jan Kierfeld
We investigate the deformation of elastic microcapsules adsorbed at liquid-liquid interfaces. An initially spherical elastic capsule at a liquid-liquid interface undergoes circumfe…
Buckling of elastic filaments by discrete magnetic moments
Horst-Holger Boltz, Stefan Klumpp
We study the buckling of an idealized, semiflexible filament along whose contour magnetic moments are placed. {We give analytic expressions for the critical stiffness of the filame…
Stationary shapes of deformable particles moving at low Reynolds numbers
Horst-Holger Boltz, Jan Kierfeld
Lecture Notes of the Summer School ``Microswimmers -- From Single Particle Motion to Collective Behaviour'', organised by the DFG Priority Programme SPP 1726 (Forschungszentrum J{ü…
Shapes of sedimenting soft elastic capsules in a viscous fluid
Horst-Holger Boltz, Jan Kierfeld
Soft elastic capsules which are driven through a viscous fluid undergo shape deformation coupled to their motion. We introduce an iterative solution scheme which couples hydrodynam…
Monte Carlo Simulation of Dense Polymer Melts Using Event Chain Algorithms
Tobias Alexander Kampmann, Horst-Holger Boltz, Jan Kierfeld
We propose an efficient Monte Carlo algorithm for the off-lattice simulation of dense hard sphere polymer melts using cluster moves, called event chains, which allow for a rejectio…
Parallelized event chain algorithm for dense hard sphere and polymer systems
Tobias Alexander Kampmann, Horst-Holger Boltz, Jan Kierfeld
We combine parallelization and cluster Monte Carlo for hard sphere systems and present a parallelized event chain algorithm for the hard disk system in two dimensions. For parallel…
Depinning of stiff directed lines in random media
Horst-Holger Boltz, Jan Kierfeld
Driven elastic manifolds in random media exhibit a depinning transition to a state with non-vanishing velocity at a critical driving force. We study the depinning of stiff directed…
Stiff directed lines in random media
Horst-Holger Boltz, Jan Kierfeld
We investigate the localization of stiff directed lines with bending energy by a short-range random potential. We apply perturbative arguments, Flory scaling arguments, a variation…
Controlling adsorption of semiflexible polymers on planar and curved substrates
Tobias A. Kampmann, Horst-Holger Boltz, Jan Kierfeld
We study the adsorption of semiflexible polymers such as polyelectrolytes or DNA on planar and curved substrates, e.g., spheres or washboard substrates via short-range potentials u…
Localization transition of stiff directed lines in random media
Horst-Holger Boltz, Jan Kierfeld
We investigate the localization of stiff directed lines with bending energy by a short-range random potential. Using perturbative arguments, Flory arguments, and a replica calculat…
