Non-reciprocal torques guide self-assembly of active particles into clusters with controllable function
Till Welker, Yukino Fujiya, Holger Stark
Self-assembly of constituents determines structure formation in the microscopic world. Attractive forces can assemble active particles into colloidal machines, but they do not fix…
Emergent collective behavior of cohesive, aligning particles
Jeanine Shea, Holger Stark
Collective behavior is all around us, from flocks of birds to schools of fish. These systems are immensely complex, which makes it pertinent to study their behavior through minimal…
Trypanosoma brucei moving in microchannels and through constrictions
Zihan Tan, Julian I. U. Peters, Holger Stark
Trypanosoma brucei (T. brucei), a single-celled parasite and natural microswimmer, is responsible for fatal sleeping sickness in infected mammals, including humans. Understanding h…
Dividing active and passive particles in nonuniform nutrient environments
Till Welker, Holger Stark
To explore the coupling between a growing population of microorganisms such as E. coli and a nonuniform nutrient distribution, we formulate a minimalistic model. It consists of act…
