Computing the Zeros of a Holomorphic Function Using Quadrature-Based Subdivision and Rational Approximation of the Logarithmic Derivative
Jake Bowhay, Yuji Nakatsukasa, Irwin Zaid
We introduce a new method that uses AAA approximation to reliably compute all the zeros of a holomorphic function in a specified search region in the complex plane. Specifically, t…
Bulk-mediated diffusion on a planar surface: full solution
Aleksei V. Chechkin, Irwin M. Zaid, Michael A. Lomholt +2
We consider the effective surface motion of a particle that intermittently unbinds from a planar surface and performs bulk excursions. Based on a random walk approach we derive the…
Effective surface motion on a reactive cylinder of particles that perform intermittent bulk diffusion
Aleksei V. Chechkin, Irwin M. Zaid, Michael A. Lomholt +2
In many biological and small scale technological applications particles may transiently bind to a cylindrical surface. In between two binding events the particles diffuse in the bu…
Lévy Fluctuations and Tracer Diffusion in Dilute Suspensions of Algae and Bacteria
Irwin M. Zaid, Jörn Dunkel, Julia M. Yeomans
Swimming microorganisms rely on effective mixing strategies to achieve efficient nutrient influx. Recent experiments, probing the mixing capability of unicellular biflagellates, re…
Swimmer-tracer scattering at low Reynolds number
Jörn Dunkel, Victor B. Putz, Irwin M. Zaid +1
Understanding the stochastic dynamics of tracer particles in active fluids is important for identifying the physical properties of flow generating objects such as colloids, bacteri…
Noisy swimming at low Reynolds numbers
Jörn Dunkel, Irwin M. Zaid
Small organisms (e.g., bacteria) and artificial microswimmers move due to a combination of active swimming and passive Brownian motion. Considering a simplified linear three-sphere…
