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…
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…
Simultaneous polydirectional transport of colloidal bipeds
Mahla Mirzaee-Kakhki, Adrian Ernst, Daniel de las Heras +6
Detailed control over the motion of colloidal particles is relevant in many applications in colloidal science such as lab-on-a-chip devices. Here, we use an external magnetic field…
Colloidal trains
Mahla Mirzaee-Kakhki, Adrian Ernst, Daniel de las Heras +10
Single and double paramagnetic colloidal particles are placed above a magnetic square pattern and are driven with an external magnetic field precessing around a high symmetry direc…
Magnetic domains without domain walls: a unique effect of He+ ion bombardment in ferrimagnetic Co/Tb multilayers
Łukasz Frąckowiak, Piotr Kuświk, Gabriel David Chaves-O'Flynn +6
We show that it is possible to engineer magnetic multi-domain configurations without domain walls in a prototypical rare earth/transition metal ferrimagnet using keV He+ ion bombar…
Edge states at the boundary between topologically equivalent lattices
Helena Massana-Cid, Adrian Ernst, Daniel de las Heras +9
Edge currents of paramagnetic colloidal particles propagate at the edge between two topologically equivalent magnetic lattices of different lattice constant when the system is driv…
Colloidal topological insulators
Johannes Loehr, Daniel de las Heras, Adam Jarosz +8
Topological insulators insulate in the bulk but exhibit robust conducting edge states protected by the topology of the bulk material. Here, we design a colloidal topological insula…
Lattice symmetries and the topological protected transport of colloidal particles
Johannes Loehr, Daniel de las Heras, Michael Loenne +10
The topologically protected transport of colloidal particles on top of magnetic patterns of all possible single lattice constant two dimensional magnetic point group symmetries is…
