Wrocław Tech Physics Seminar – 7th of April 2025

We cordially invite you to Wrocław University of Science and Technology Physics Seminar on Monday 7th of April 2025 at 11:15 in room 322, building A-1, where there will be delivered a lecture:

Optical levitation and cooling of nanoparticles
 
Prof. Pavel Zemánek
Czech Academy of Sciences, Institute of Scientific Instruments, Brno
 
Please find an abstract below.
 
 
The seminar will focus on the force interaction between light and nanoparticles in vacuum. Though such optical forces are tiny, they can levitate a nanoparticle in the light. Such optical levitation in vacuum isolates the nanoparticle from the noisy environment around and the nanoparticle behaves as a weakly damped tiny oscillator. Using various optomechanical interactions, the amplitude of nanoparticle oscillations can be decreased, and even the lowest energy levels allowed by quantum mechanics can be reached. Recent experiments have already succeeded in revealing such a „macroscopic quantum oscillator“ and have opened the experimental doors to the unexplored boundary between quantum and classical worlds.
