Experimental Search for Quantum Gravity

Dr. Sabine Hossenfelder is a research fellow at the Frankfurt Institute for Advanced Studies. Her research focuses on topics ranging from the physics of black holes to cosmology to the foundations of quantum mechanics. She devoted more than ten years to investigate the question where to best search for experimental evidence of quantum gravity. She worked at Nordita (Nordic Institute for Theoretical Physics), Stockholm, Sweden; the Perimeter Institute, Waterloo, Ontario, Canada; the University of California, Santa Barbara, USA and at the University of Arizona, USA.Contributing Authors:​Matthias Lorenz, Commissariat à l'énergie atomique CEA Saclay, FranceDavid Brizuela, Manuel Kraemer, University of the Basque Country, SpainTim Lappe, University of Bonn, GermanyFabian Mueller, Institute of Mathematics, University Frankfurt, GermanyFabienne Schneiter,University Tübingen, GermanyGiacomo D'Amico, Università di Roma La Sapienza, ItalyJosé Manuel Carmona, Universidad de Zaragoza, SpainAlexander Maximilian Eller, Darmstadt University of Technology, GSI Helmholtz Center, GermanyHelena Schmidt, German National Metrologic Institute (PTB), Berlin, Germany Giovanni Amelino-Camelia, Dipt Fisica, Sapienza University of Rome, ItalySabina Scully, Australian National University, AustraliaAntonia Micol Frassino, Frankfurt Institute for Advanced Studies (FIAS) andUniversity Frankfurt, GermanyMatteo Trudu, University of Cagliari, ItalyMartin Seltmann, Technical University (TU) Munich, GermanyManon Bischoff, University Mainz, GermanyMichael Florian Wondrak, FIAS, Frankfurt, Germany
