Abstract:
We will start by giving a pedagogical introduction to the description of 3D objects such as nanoparticles. We will introduce the basic concepts required to write the dynamics for the roto-translational degrees of freedom in a Hamiltonian form. We will then proceed to show how to obtain a complete description of all the optomechanical forces and torques for anisotropic particles in a classical setting. In particular, starting from the classical optomechanical interaction, we will recover the gradient and radiation pressure forces and torques as well as the recoil heating of translations and rotations. We will conclude by briefly highlighting how such effects change as we change the particle shape and size in experiments.
