Atomic Theory for Fundamental Interactions and Simple Systems in Strong Fields

426th Wilhelm and Else Heraeus Seminar

January 18 - 21, 2009

Physik Zentrum Bad Honnef, Germany

Funded by the Wilhelm and Else Heraeus Stiftung

 

This workshop aims to bring together experts, post-doc's and students from the theory of fundamental interactions and simple atomic systems in order to discuss the recent advancements and the open problems in this vital field. Central topics of the seminar are:

  • Quantum elektrodynamics for simple atomic systems (exotic atoms, g-factors, hyperfine structure in highly-charge hydrogen- and lithium-like ions)
  • Tests on the elektro-weak interaction (parity and time-reversal violation, non-VA contributions to the "beta" decay, ...)
  • Tests of fundamental symmetries (CPT, g-factor of antihydrogen, permanent electrie-dipole moments, time-dependence of fundamental constants)
  • Determination of fundamental constants

With FAIR, the International Facility for Antiproton and Ion Research in Darmstadt, there will be established a world-wide unique place during the next years where intensive ion beams with very high brilliance become available. This facility will allow novel studies on th fundamental symmetries and light-matter interaction in the presence of strong and supercritical fields. With this seminar, we wish to stimulate discussions and to initiate collaborations between groups to exploit the features of the FAIR and other facilities.

Apart from the success and advantanges of the theoretical methods and approximations, all speakers are ask to access critical the weak points and limitations of the theory.

 

Organizers:

  • Stephan Fritzsche (GSI Darmstadt)
  • Paul Indelicato (Ecole Normale, Paris)
  • Alejandro Saenz (HU Berlin)
