Observation of polarization singularities and topological textures in sound waves
R. D. Muelas-Hurtado, K. Volke-Sepulveda, J. L. Ealo +4
Polarization singularities and topological polarization structures are generic features of inhomogeneous vector wave fields of any nature. However, their experimental studies mostl…
Optical Tweezers: A Comprehensive Tutorial from Calibration to Applications
Jan Gieseler, Juan Ruben Gomez-Solano, Alessandro Magazzù +9
Since their invention in 1986 by Arthur Ashkin and colleagues, optical tweezers have become an essential tool in several fields of physics, spectroscopy, biology, nanotechnology, a…
Light control through a nonlinear lensing effect in a colloid of biosynthesized Gold Nanoparticles
A. Balbuena Ortega, E. Brambilia, V. López Gayou +5
Biosynthesis of four samples of colloidal suspensions of gold nanoparticles is achieved using hydroalcoholic extract and three different separated compounds of the plant Bacopa pro…
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…
A new type of light with enhanced optical chirality
Carmelo Rosales-Guzmán, Karen Volke-Sepulveda, Juan P. Torres
Recently, Tang and Cohen (Science 332, 333, 2011) have demonstrated a scheme to enhance the chiral response of molecules, which relies on the use of circularly polarized light in a…
Brownian motion in typical microparticle systems
Silvana Palacios, Victor Romero-Rochin, Karen Volke-Sepulveda
Many studies on microscopic systems deal with Brownian particles embedded in media whose densities are different from that of the particles, causing them either to sink or float. T…
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…
All-optical 3D atomic loops generated with Bessel light fields
K. Volke-Sepulveda, R. Jauregui
The propagation invariance of Bessel beams as well as their transversal structure are used to perform a comparative analysis of their effect on cold atoms for four different config…
