ITMO Physicists Use Radiofrequency Trap to “Freeze” Nanocrystals
A group of physicists from ITMO University has developed a system that provides optical cooling to nanocrystals. The system, made up of a radiofrequency trap and a laser light source, decreases the kinetic energy of a nanocrystal and lowers it to its quantum limit, at which new properties emerge. This method may prove useful in fundamental research and studies of biological objects within the framework of quantum mechanics. A research paper was published in the Journal of the Optical Society of America B as an editors’ pick.

COMSOL DAY: Tractor Beams, Optical Traps and Nanoparticle Manipulation
At the COMSOL Day in Moscow, head of ITMO’s International Research Laboratory of Nano-Opto-Mechanics Alexander Shalin gave a talk on the new algorithms for multiphysics modeling and optical power calculations using COMSOL Multiphysics software. He demonstrated how the program can be used to model the excitement of unidirectional surface plasmon-polaritons and their optomechanical effect on nano-objects on metal surfaces. Shalin’s team uses these methods to acquire fundamental results in optomechanics and improve the qualities of such technologies as tractor beams, optical trapping, positioning of nanoparticles and other.
