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…
Defect Dynamics in Artificial Colloidal Ice: Real-Time Observation, Manipulation and Logic Gate
Johannes Loehr, Antonio Ortiz-Ambriz, Pietro Tierno
We study the defect dynamics in a colloidal spin ice system realized by filling a square lattice of topographic double well islands with repulsively interacting magnetic colloids.…
Topologically protected colloidal transport above a square magnetic lattice
Daniel de las Heras, Johannes Loehr, Michael Loenne +1
We theoretically study the motion of magnetic colloidal particles above a magnetic pattern and compare the predictions with Brownian dynamics simulations. The pattern consists of a…
Topological protection of multiparticle dissipative transport
Johannes Loehr, Michael Loenne, Adrian Ernst +2
Topological protection allows robust transport of localized phenomena such as quantum information, solitons, and dislocations. The transport can be either dissipative or non-dissip…
