Thermodynamics of a Colloidal Particle in a Time-Dependent Non-Harmonic Potential
V. Blickle, T. Speck, L. Helden +2
We study the motion of an overdamped colloidal particle in a time-dependent non-harmonic potential. We demonstrate the first law-like balance between applied work, exchanged heat,…
Noise enhanced performance of ratchet cellular automata
Dusan Babic, Clemens Bechinger
We present the first experimental realization of a ratchet cellular automaton (RCA) which has been recently suggested as an alternative approach for performing logical operations w…
New Light on Like-Charge Attraction
Joerg Baumgartl, Jose Luis Arauz-Lara, Clemens Bechinger
We report on pair interaction measurements in charged colloidal systems in confined and unconfined geometries by means of optical microscopy. At very small particle distances we ob…
