Testing Quantum Electrodynamics with Exotic Atoms

Simple Atoms, Quantum Electrodynamics and Fundamental Constants

This review is devoted to precision physics of simple atoms. The atoms can essentially be described in the framework of quantum electrodynamics (QED), however, the energy levels are also affected by the effects of the strong interaction due to the nuclear structure. We pay special attention to QED tests based on studies of simple atoms and consider the influence of nuclear structure on energy l...

Quantum Electrodynamics and Exotic Atomic Phenomena of High

We review the physics of the exotic atomic phenomena, especially positron autoionization,which can occur if the charge of the nucleus is increased beyond the critical value Z 170. The adiabatic collision of two heavy ions can be used to study experimentally the problem of the Dirac electron in a Coulomb field beyond the critical value where pair production occurs. Various approaches to this phe...

Exotic Atoms and Exotic Nuclei

Exotic atoms

In this paper I review a number of recent results in the field of exotic atoms. Recent experiments or ongoing experiments with muonic, pionic and antiprotonic hydrogen, as well as recent measurement of the pion mass are described. These experiments provide information about nucleon-pion or nucleonantinucleon interaction as well as information on the proton structure (charge or magnetic moment d...

Cavity Quantum Electrodynamics of Continuously Monitored Bose-Condensed Atoms

We study cavity quantum electrodynamics of Bose-condensed atoms that are subjected to continuous monitoring of the light leaking out of the cavity. Due to a given detection record of each stochastic realization, individual runs spontaneously break the symmetry of the spatial profile of the atom cloud and this symmetry can be restored by considering ensemble averages over many realizations. We s...
