10-19: Mishkatul Bhattacharya from the Rochester Institute of Technology tells us about how to engineer a phonon laser
Optical Tweezer Phonon Laser
Abstract: We are in the middle of a revolution in phononics, where it seems useful and possible to control phonons as we have photons in the last few decades. In this talk
I will describe our theoretical proposal and its experimental demonstration regarding
a phonon laser made of the center-of-mass oscillations of a nanoparticle trapped in an
optical tweezer. I will report on threshold behavior, coherence, subthermal number
squeezing, time dynamics, phase space characterization, injection locking, Q switching
and the role of stimulated emission in our single mode phonon laser. Based on this discussion
I will conclude that our device provides a pathway for engineering a coherent source of
phonons on the mesoscale that can be applied to both fundamental problems in quantum
mechanics as well as tasks of precision metrology.
