Energy relaxation in hot electron quantum optics via acoustic and optical phonon emission

Dr Lewis Clark, School of Mathematics, Statistics and Physics, Newcastle University.

Dr Lewis Clark, School of Mathematics, Statistics and Physics, Newcastle University, will be presenting a seminar on his research. All welcome to attend.

We study theoretically the relaxation of hot quantum-Hall edge-channel electrons under the emission of both acoustic and optical phonons. Aiming to model recent experiments with single-electron sources, we present simulations that provide the distribution of electron energies and arrival times at a detector a fixed distance from the source. Furthermore, we consider the mean energy loss due to acoustic phonon emission and resultant broadening of the electron energy distribution and derive an effective drift-diffusion model for this process.
