Active Cloaking in Stokes Flows via Reinforcement Learning
Mehdi Mirzakhanloo, Soheil Esmaeilzadeh, Mohammad-Reza Alam
Hydrodynamic signatures at the Stokes regime, pertinent to motility of micro-swimmers, have a long-range nature. This implies that movements of an object in such a viscosity-domina…
Frequency-dependent higher-order Stokes singularities near a planar elastic boundary: implications for the hydrodynamics of an active microswimmer near an elastic interface
Abdallah Daddi-Moussa-Ider, Christina Kurzthaler, Christian Hoell +6
The emerging field of self-driven active particles in fluid environments has recently created significant interest in the biophysics and bioengineering communities owing to their p…
The Experimental Realization of an Artificial Low-Reynolds-Number Swimmer with Three-Dimensional Maneuverability
Mohsen Saadat, Mehdi Mirzakhanloo, Julie Shen +2
The motion of biological micro-robots -- similar to that of swimming microorganisms such as bacteria or spermatozoa -- is governed by different physical rules than what we experien…
Stealthy Movements and Concealed Swarms of Swimming micro-Robots
Mehdi Mirzakhanloo, Mohammad-Reza Alam
Here we show that micro-swimmers can form a concealed swarm through synergistic cooperation in suppressing one another's disturbing flows. We then demonstrate how such a concealed…
Flow Characteristics of Chlamydomonas result in Purely Hydrodynamic Scattering
Mehdi Mirzakhanloo, Mohammad-Reza Alam
It has long been believed that swimming eukaryotes feel solid boundaries through direct ciliary contact. Specifically, based on observations of behavior of green alga Chlamydomonas…
