Globally aligned states and hydrodynamic traffic jams in confined suspensions of active asymmetric particles
Globally aligned states and hydrodynamic traffic jams in confined suspensions of active asymmetric particles
Strongly confined active liquids are subject to unique hydrodynamic interactions due to momentum screening and lubricated friction by the confining walls. Using numerical simulations, we demonstrate that two-dimensional dilute suspensions of fore-aft asymmetric polar swimmers in a Hele-Shaw geometry can exhibit a rich variety of novel phase behaviors depending on …
