“…The importance of the decay rates of a metastable state in the precision atomic spectroscopy has been repeatedly demonstrated in the literature. For instance, the emission of hydrogen and hydrogen-like atoms under the influence of external electric and magnetic fields has been the subject of research on parity nonconservation (PNC) effects since [12][13][14]. Another application relates to the measurement of the Lamb shift in the hydrogen atom and HCI by resorting to emission interference [13,15].…”

The effect of a constant magnetic ﬁeld in combination with a ﬁeld induced by an external thermal environment on atomic decay rates is studied. For this purpose, radiative corrections including magnetic interaction are considered for hydrogen and hydrogen-like ions with a small nuclear charge Z. Corrections to the decays of the metastable state 2s and the excited state 2p were calculated at various magnetic ﬁeld strengths suitable for the conditions of the laboratory experiments. It is found that the combination of the magnetic ﬁeld and thermal environment can lead to a broadening close to the level of experimental error, which makes it necessary to take them into account in the near future.

“…The original AC effect was for a particle with spin and a non-zero anomalous magnetic dipole moment (MDM) interacting with a two dimensional electric field perpendicular to the spin polarization direction. It was realized that spin 1/2 is a particularly simple and instructive case, but the AC effect and other related effects have also been studied for particles with different spins [5][6][7][8][9][10][11].…”

The original topological Aharonov-Casher (AC) effect is due to the interaction of the anomalous magnetic dipole moment (MDM) with certain configurations of electric field. Naively one would not expect an AC effect for a scalar particle for which no anomalous MDM can be defined in the usual sense. In this letter we study the AC effect in supersymmetric systems. In this framework there is the possibility of deducing the AC effect of a scalar particle from the corresponding effect for a spinor particle. In 3+1 dimensions such a connection is not possible because the anomalous MDM is zero if supersymmetry is an exact symmetry. However, in 2+1 dimensions it is possible to have an anomalous MDM even with exact supersymmetry.Having demonstrated the relationship between the spinor and the scalar MDM, we proceed to show that the scalar AC effect is uniquely defined.We then compute the anomalous MDM at the one loop level, showing how the scalar form arises in 2+1 dimensions from the coupling of the scalar to spinors. This model shows how an AC effect for a scalar can be generated for
