Fast and rewritable colloidal assembly via field synchronized particle swapping
Pietro Tierno, Tom H. Johansen, Thomas M. Fischer
We report a technique to realize reconfigurable colloidal crystals by using the controlled motion of particle defects above an externally modulated magnetic substrate. The transpor…

Excluded volume causes integer and fractional plateaus in colloidal ratchet currents
Pietro Tierno, Thomas M. Fischer
We study the collective transport of paramagnetic colloids driven above a magnetic bubble lattice by an external rotating magnetic field. We measure a direct ratchet current which…
