Photon position observable
Margaret Hawton, Vincent Debierre
In biorthogonal quantum mechanics, the eigenvectors of a quasi-Hermitian operator and those of its adjoint are biorthogonal and complete and the probability for a transition from a…
Mid- and far-field deviations from causality in spontaneous light emission by atomic Hydrogen
Vincent Debierre, Thomas Durt
We investigate, in the case of the transition in atomic Hydrogen, the behaviour of the spontaneously emitted electromagnetic field in spacetime. We focus…
Spontaneous light emission by atomic Hydrogen: Fermi's golden rule without cheating
V. Debierre, T. Durt, A. Nicolet +1
Focusing on the transition in atomic Hydrogen, we investigate through first order perturbation theory the time evolution of the survival probability of an…
Fermi golden rule beyond the Zeno regime
Vincent Debierre, Isabelle Goessens, Édouard Brainis +1
We reconsider the problem of the spontaneous emission of light by an excited atomic state. We scrutinize the survival probability of this excited state for very short times, in the…
