Cold damping of levitated optically coupled nanoparticles
Vojtech Liska, Tereza Zemankova, Vojtech Svak +6
Methods for controlling the motion of single particles, optically levitated in vacuum, have developed rapidly in recent years. The technique of cold damping makes use of feedback-c…
Synchronization of spin-driven limit cycle oscillators optically levitated in vacuum
Oto Brzobohaty, Martin Duchan, Petr Jakl +3
We explore, experimentally and theoretically, the emergence of coherent coupled oscillations and synchronization between a pair of non-Hermitian, stochastic, opto-mechanical oscill…
Bayesian Estimation of Experimental Parameters in Stochastic Inertial Systems: Theory, Simulations, and Experiments with Objects Levitated in Vacuum
Martin Šiler, Vojtěch Svak, Alexandr Jonáš +3
High-quality nanomechanical oscillators can sensitively probe force, mass, or displacement in experiments bridging the gap between the classical and quantum domain. Dynamics of the…
All-optical sub-Kelvin sympathetic cooling of a levitated microsphere in vacuum
Yoshihiko Arita, Graham D. Bruce, Ewan M. Wright +3
We demonstrate all-optical sympathetic cooling of a laser-trapped microsphere to sub-Kelvin temperatures, mediate by optical binding to a feedback-cooled adjacent particle. Our stu…
Challenges on Optical Printing of Colloidal Nanoparticles
Ianina L. Violi, Luciana P. Martinez, Mariano Barella +14
While colloidal chemistry provides ways to obtain a great variety of nanoparticles, with different shapes, sizes, material composition, and surface functions, their controlled depo…
Nanovortex-driven all-dielectric optical diffusion boosting and sorting concept for lab-on-a-chip platforms
Adrià Canós Valero, Denis Kislov, Egor A. Gurvitz +5
The ever-growing field of microfluidics requires precise and flexible control over fluid flow at the micro- and nanoscales. Current constraints demand a variety of controllable com…
Tunable soft-matter optofluidic waveguides assembled by light
Oto Brzobohaty, Lukas Chvatal, Alexandr Jonas +4
Development of artificial materials exhibiting unusual optical properties is one of the major strands of current photonics research. Of particular interest are soft-matter systems…
Diffusing Up the Hill: Dynamics and Equipartition in Highly Unstable Systems
Martin Šiler, Luca Ornigotti, Oto Brzobohatý +5
Stochastic motion of particles in a highly unstable potential generates a number of diverging trajectories leading to undefined statistical moments of the particle position. This m…
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…
Thermally induced passage and current of particles in a highly unstable optical potential
Artem Ryabov, Pavel Zemanek, Radim Filip
We discuss the statistics of first-passage times of a Brownian particle moving in a highly unstable nonlinear potential proportional to an odd power of position. We observe tempera…
Optical sorting and detection of sub-micron objects in a motional standing wave
Tomas Cizmar, Martin Siler, Mojmir Sery +3
An extended interference pattern close to surface may result in both a transmissive or evanescent surface fields for large area manipulation of trapped particles. The affinity of d…
