Integer defects in active nematics of ellipsoidal Quincke rollers
Bao Ying Fan, Lin Liu, Jie Wu +4
Transverse propulsion changes topological ordering in dense ellipsoidal Quincke rollers. Under an alternating-current electric field, a polar velocity field coexists with perpendic…

Activity Waves in Condensed Phases of Quincke Rollers
Meng Fei Zhang, Bao Ying Fan, Zeng Tao Liu +1
Wave-exciting is a universal phenomenon in physical and biological excitable systems. Here we show that colloidal systems of Quincke rollers which are driven periodically can conde…
