时间: 5月20日 (星期二) 下午2:00Quantum optomechanics is rapidly developing into a major area of research at the boundary between quantum optics, nanoscience, ultracold science, and quantum metrology. This is a result of a convergence from two perspectives on the physical world. From the top down, ultra-sensitive micromechanical and nanomechanical detectors have become available utilizing the advanced materials and processing techniques of the semiconductor industry and nanoscience. From the bottom-up perspective, quantum optics and atomic physics have yielded an exquisite understanding of the mechanical aspects of light–matter interaction, including how quantum mechanics limits the ultimate sensitivity of measurements and how back- action—the influence a quantum measurement necessarily exerts on the object being measured— can be harnessed to control quantum states of mechanical systems. As a result quantum optomechanics offers considerable potential both in fundamental and in applied science, with the promise of sensors capable of probing extremely feeble forces, often with spatial resolution at atomic scales.

After a general tutorial introduction, the talk will discuss selected recent developments, concentrating primarily on studies of the quantum-classical interface and of quantum thermodynamics.
