Transition path time over a barrier of a colloidal particle in a viscoelastic bath
Brandon R. Ferrer, Alejandro V. Arzola, Denis Boyer +1
We experimentally study the statistics of the transition path time taken by a submicron bead to successfully traverse an energy barrier created by two optical tweezers in two proto…
Fluid viscoelasticity triggers fast transitions of a Brownian particle in a double well optical potential
Brandon R. Ferrer, Juan Ruben Gomez-Solano, Alejandro V. Arzola
Thermally activated transitions are ubiquitous in nature, occurring in complex environments which are typically conceived as ideal viscous fluids. We report the first direct observ…
Omnidirectional Transport in Fully Reconfigurable Two Dimensional Optical Ratchets
Alejandro V. Arzola, Mario Villasante-Barahona, Karen Volke-Sepúlveda +2
A fully reconfigurable two-dimensional (2D) rocking ratchet system created with holographic optical micromanipulation is presented. We can generate optical potentials with the geom…
Dynamical analysis of an optical rocking ratchet: Theory and experiment
Alejandro V. Arzola, Karen Volke-Sepúlveda, José L. Mateos
A thorough analysis of the dynamics in a deterministic optical rocking ratchet (introduced in A. V. Arzola et al., Phys. Rev. Lett. 106, 168104 (2011)) and a comparison with experi…
Experimental Control of Transport and Current Reversals in a Deterministic Optical Rocking Ratchet
Alejandro V. Arzola, Karen Volke-Sepúlveda, José L. Mateos
We present an experimental demonstration of a deterministic optical rocking ratchet. A periodic and asymmetric light pattern is created to interact with dielectric microparticles i…
