Introduction
摘要
Quantum mechanics predicts an infinite number of random fluctuations in vacuum because of the zero-point energy of the electromagnetic fields. Quantum vacuum fluctuations lead to the Casimir force between two neutral macroscopic objects, the Casimir torque between two anisotropic bodies, and the quantum vacuum friction between two moving bodies. In this thesis, we focus on using optomechanical systems (the multi-cantilever system and the levitated optomechanical system) to study Casimir force, Casimir torque, and quantum vacuum friction.
