The breakthrough of laser cooling technique of atoms is followed by the quantum-mechanical control center-of-mass motions of macroscopic objects.
This course covers the introduction of current research on the optomechanical cooling and control of mechanical oscillators as well as the basic theory to study these quantum systems including quantum-optical methods, and non-equilibrium quantum statistical physics.
We expect students to:
― Understand the basic principle of cavity control of mechanical oscillators.
― Learn the basic theoretical methods to describe the quantized electromagnetic fields, random motions, and open quantum systems.
Non-equilibrium quantum statistical physics, quantum optics, nonlinear dynamics, cavity quantum electrodynamics, cavity optomechanics
