Machine-learned topological transport of magnetic colloids
Sebastian Wohlrab, Aneena Rinu Perayil, Piotr Kuświk +6
By modulating the orientation of a uniform magnetic field it is possible to transport magnetic microparticles above magnetic patterns. In periodic patterns, driving control loops t…
Topological sorting of magnetic colloidal bipeds
Aneena Rinu Perayil, Piotr Kuświk, Maciej Urbaniak +5
Topologically nontrivial adiabatic loops of the orientation of a homogeneous external magnetic field drive the walking of paramagnetic colloidal bipeds above a deformed quasi-perio…
Topologically cloaked magnetic colloidal transport
Anna M. E. B. Rossi, Thomas Märker, Nex C. X. Stuhlmüller +8
Cloaking is a method of making obstacles undetectable. Here we cloak unit cells of a magnetic pattern squeezed into an otherwise periodic pattern from a magnetically driven colloid…
Magnetic colloidal single particles and dumbbells on a tilted washboard moire pattern in a precessing external field
Farzaneh Farrokhzad, Nex C. X. Stuhlmüller, Piotr Kuświk +6
We measure the dynamical behavior of colloidal singlets and dumbbells on an inclined magnetic moiré pattern, subject to a precessing external homogeneous magnetic field. At low ext…
Topologically controlled synthesis of active colloidal bipeds
Jonas Elschner, Farzaneh Farrokhzad, Piotr Kuświk +6
Topological growth control allows to produce a narrow distribution of outgrown colloidal rods with defined and adjustable length. We use an external magnetic field to assemble para…
Disorder scattering in classical flat channel transport of particles between twisted magnetic square patterns
Anna M. E. B. Rossi, Adrian Ernst, Magdalena Dörfler +1
We measure the trajectories of macroscopic magnetic particles pulled against gravity between twisted alternating magnetic square patterns in a superposed homogeneous magnetic field…
Simultaneous and independent topological control of identical microparticles in non-periodic energy landscapes
N. C. X. Stuhlmüller, F. Farrokhzad, P. Kuświk +6
Topological protection ensures stability of information and particle transport against perturbations. We explore experimentally and computationally the topologically protected tran…
