Charge decoherence in laterally coupled quantum dots due to electron-phonon interactions
Charge decoherence in laterally coupled quantum dots due to electron-phonon interactions
We investigate electron charge decoherence in a laterally-coupled single-electron semiconductor double quantum dot through electron-phonon interaction. We analytically and numerically evaluate the relaxation and dephasing rates due to electron coupling to both acoustic and optical phonons, and explore the system parameter space in terms of interdot distance, strength of single-dot …
