Ericson fluctuations in an open, deterministic quantum system: theory meets experiment — •Javier Madronero1 and Andreas Buchleitner2 — 1Physik Department, Technische Universität München — 2Max-Plank-Institut für Physik komplexer Systeme, Dresden
We report on numerically exact quantum calculations on alkali Rydberg atoms in crossed magnetic and electric fields, above the ionization threshold in a regime of overlapping resonances. The calculated photoexcitation cross sections for rubidium Rydberg states are in quantitative agreement with recent experimental observations [1] and exhibit a clear transition towards the Ericson regime [2].
