Field-controlled randomness of colloidal paths on a magnetic bubble lattice

Antipersistent Random Walk in a Two State Flashing Magnetic Potential

“…2, a particle can jump to 6 possible places [top of . In both states, the potential preserves its spatial symmetry; i.e., no dynamical symmetry breaking occurs unlike what happens in [12,14], and after N cycles the particle motion resembles a random walk on a hexagonal lattice, as shown in Fig. 1(b) (see video in [13]).…”
