Directed transport with real-time steering and drifts along pre-designed paths using a Brownian motor
H. Hagman, M. Zelan, C. M. Dion +1
We have realized real-time steering of the directed transport in a Brownian motor based on cold atoms in optical lattices, and demonstrate drifts along pre-designed paths. The tran…
Experimental measurement of efficiency and transport coherence of a cold atom Brownian motor in optical lattices
M. Zelan, H. Hagman, G. Labaigt +2
The rectification of noise into directed movement or useful energy is utilized by many different systems. The peculiar nature of the energy source and conceptual differences betwee…
Breaking the symmetry of a Brownian motor with symmetric potentials
H. Hagman, M. Zelan, C. M. Dion
The directed transport of Brownian particles requires a system with an asymmetry and with non-equilibrium noise. We here investigate numerically alternative ways of fulfilling thes…
Fluctuation-induced drift in a gravitationally tilted optical lattice
M. Zelan, H. Hagman, K. Karlsson +2
Experimental and theoretical studies are made of Brownian particles trapped in a periodic potential, which is very slightly tilted due to gravity. In the presence of fluctuations,…
Influence of the lattice topography on a three-dimensional, controllable Brownian motor
H. Hagman, C. M. Dion, P. Sjolund +2
We study the influence of the lattice topography and the coupling between motion in different directions, for a three-dimensional Brownian motor based on cold atoms in a double opt…
Characterisation of a three-dimensional Brownian motor in optical lattices
P. Sjolund, S. J. H. Petra, C. M. Dion +3
We present here a detailed study of the behaviour of a three dimensional Brownian motor based on cold atoms in a double optical lattice [P. Sjolund et al., Phys. Rev. Lett. 96, 190…
