In recent years, the urgency of understanding the nature of dark matter, whose mass in our galaxy significantly exceeds that of the normal matter, has become particularly clear. In view of the fact that the weakly interacting massive particles (WIMPs), the primary dark matter candidate for decades, have not been seen, there is great interest in looking for alternative frameworks, particularly, that of ultralight bosonic fields. The (scientific rather than bosonic) field is "bubbling" with new ideas, both on the side of theoretical advances and new experimental concepts. The purpose of this school is to orient newcomers to the field, especially graduate students and post-docs and, in addition to formal lectures, to provide an opportunity for informal interactions with some of the leading scientists working on the cutting edge of ultralight bosonic dark matter research

Topics and lecturers include:

  • Kick-off talk: Phenomenology of dark matter and emerging detection modalities, Marianna Safronova (University of Delaware, USA)
  • Axion models and the historical development of bosonic dark matter in contrast to WIMPs, Felix Yu (University of Mainz, Germany)
  • Light-shining-through-walls Experiments, Gulden Othman (DESY Hamburg, Germany)
  • Microwave Cavity Searches, Karl van Bibber (University of California, Berkeley USA)
  • Theoretical overview of ultralight dark matter, Maxim Pospelov (Perimeter Institute, Waterloo, Ontario, Canada)
  • Cosmology of ultralight DM, astrophysical searches and constraints, David J. E. Marsh (King’s College London, UK)
  • Helioscopes, Manuel Meyer (DESY, Hamburg, Germany)
  • Relaxions, halos and all the rest, Gilad Perez (Weizmann Institute of Science, Rehovot, Israel)
  • Microwave cavity searches 2, Karl van Bibber (University of California, Berkeley USA)
  • Alternative explanations e.g. Modified Newtonian Dynamics, Federico Lelli (Arcetri Astrophyiscal Observatory, INAF, Italy)
  • New observables of ultralight dark matter, Marianna Safronova (University of Delaware, USA)
  • Magnetic resonance searches, Deniz Aybas (University of California, Berkeley, USA)
  • Magnetic calorimetry and its sensitivity to bosonic dark matter, Loredana Gastaldo (University of Heidelberg, Germany)
  • Matter-wave interferometry for dark energy and dark matter research, Philipp Haslinger (TU Wien, Vienna, Austria)
  • More phenomenology of ultralight bosonic dark matter, Maxim Pospelov (Perimeter Institute, Waterloo, Ontario, Canada)
