Hidden periodicities allow the prediction of locked particle motions on quasicrystalline surfaces
Seemant Mishra, Artem Ryabov, Philipp Maass
Motion of particles across quasicrystalline surfaces exhibits peculiar features due to the presence of long-range order without translational periodicity. Under time-periodic forci…
Current reversals in driven lattice gases and Brownian motion
Moritz Wolf, Sören Schweers, Philipp Maass
Particle currents flowing against an external driving are a fascinating phenomenon in both single-particle and interacting many-particle systems. Underlying physical mechanisms of…
Universal time-temperature scaling of conductivities in random site energy and associated random barrier model
Sven Lohmann, Quinn Emilia Fischer, Justus Leiber +1
Universal time-temperature scaling of conductivity spectra in disordered solids has been explained by thermally activated hopping of noninteracting particles over random energy bar…
Nonequilibrium phase transition in single-file transport at high crowding
Annika Vonhusen, Sören Schweers, Artem Ryabov +1
Driven particle transport in crowded and confining environments is fundamental to diverse phenomena across physics, chemistry, and biology. A main objective in studying such system…
Cluster sizes, particle displacements and currents in transport mediated by solitary cluster waves
Alexander P. Antonov, Annika Vonhusen, Artem Ryabov +1
In overdamped particle motion across periodic landscapes, solitary cluster waves can occur at high particle densities and lead to particle transport even in the absence of thermal…
Engineering tunable fractional Shapiro steps in colloidal transport
Andris P. Stikuts, Seemant Mishra, Artem Ryabov +2
Shapiro steps are quantized plateaus in the velocity-force or velocity-torque curve of a driven system, when its speed remains constant despite an increase in the driving force. Fo…
