Optomechanics with Levitated Nanoparticles: Cooling, Lasing and Sensing

The lecture of Dr. Mishkat Bhattacharya from Rochester Institute of Technology, Rochester, NY, USA will take place on 25.5.2023, 10:00, in the lecture hall of the ISI of the CAS.

Abstract:
In this talk I will describe our recent theoretical work on levitated optomechanics with nanoparticles. I will address cooling and regenerative center-of-mass motion (phonon lasing) theory and its relation to the experiments in the group of our collaborator A. N.
Vamivakas at the University of Rochester. I will also discuss recent standalone theory with respect to Q-switching of the phonon laser and the realization of PT-symmetry using two-mode coupling of the nanoparticle vibrations.
