Effects of on-center impurity on energy levels of low-lying states in concentric double quantum rings
In this paper, the electronic eigenstates and energy spectra of single and two-interacting electrons confined in a concentric double quantum rings with a perpendicular magnetic field in the presence of on-center donor and acceptor impurities are calculated using the exact diagonalization method. For a single electron case, the binding energy of on-center donor and acceptor impurities ar...

متن کاملComment on "Quantum electrodynamics based on self-energy: Lamb shift and spontaneous emission without field quantization"
In classical electrodynamics the radiative processes are calculated from the self-energy of the electron in external fields. In contrast, in quantum electrodynamics, the selfenergy is first thrown away and one begins with bare particles; then the self-energy is put back in photon by photon, hence the use of perturbation theory. Recently, it has been argued that. one ought also to be able to dev...

متن کاملThe Lamb Shift and Ultra High Energy Cosmic Rays
On the analogy with the Lamb shift, we study the vacuum effect that proton’s electric field interacts with virtual particles in the vacuum. We find a possible quantum instability that triggered by an external force, proton’s electric field interacting with virtual particles spontaneously induces a quantum force that back reacts on the proton in the direction of the external trigger force. Such ...
