In previous years, I have published four works that explore various protocols and ideas for quantum dynamical control in a model-independent context. This included one work [1] particularly focused on the dynamics when the characteristic frequency of a quantum emitter inside a waveguide matches the cutoff frequency inside of that waveguide, which is a universal result. A key factor influencing the dynamics in this case is an exceptional point (EP) appearing directly at the cutoff.
In this year, I have extended this work to the specific case of the classical radiation damping of a charged particle undergoing cyclotron motion inside a rectangular waveguide [2]. Note that one of the main results of our paper Ref. [2] is to show that the quantum and classical cases can be treated almost analogously. The final work on the production of the optical vortex in a cylindrical waveguide will be published in the near future. And a separate work on the general problem of radiation damping in generic classical systems will also be published in the future.
