Observation of Flux Reversal in a Symmetric Optical Thermal Ratchet
Sang-Hyuk Lee, Kosta Ladavac, Marco Polin +1
We demonstrate that a cycle of three holographic optical trapping patterns can implement a thermal ratchet for diffusing colloidal spheres, and that the ratchet-driven transport di…
Colloidal electroconvection in a thin horizontal cell
Yilong Han, David G. Grier
Applying an electric field to an aqueous colloidal dispersion establishes a complex interplay of forces among the highly mobile simple ions, the more highly charged but less mobile…
Configurational temperatures and interactions in charge-stabilized colloid
Yilong Han, David G. grier
We demonstrate that the configurational temperature formalism can be derived from the classical hypervirial theorem, and introduce a hierarchy of hyperconfigurational temperature d…
Anomalous interactions in confined charge-stabilized colloid
David G. Grier, Yilong Han
Charge-stabilized colloidal spheres dispersed in weak 1:1 electrolytes are supposed to repel each other. Consequently, experimental evidence for anomalous long-ranged like-charged…
Transport and Fractionation in Periodic Potential-Energy Landscapes
Kosta Ladavac, Matthew Pelton, David G. Grier
Objects driven through periodically modulated potential-energy landscapes in two dimensions can become locked in to symmetry-selected directions that are independent of the driving…
Microoptomechanical pumps assembled and driven by holographic optical vortex arrays
Kosta Ladavac, David G. Grier
Beams of light with helical wavefronts can be focused into ring-like optical traps known as optical vortices. The orbital angular momentum carried by photons in helical modes can b…
