Immanuel Bloch (born 16 November 1972 in Fulda, Germany) is an experimental physicist from Germany. His research is focussed on the investigation of quantum many-body systems using ultracold atomic and molecular quantum gases.
Immanuel Bloch is known for his work on ultracold atoms in artificial crystals of light, so called optical lattices and especially the first realization of a quantum phase transition from a weakly interacting superfluid to a strongly interacting Mott insulating state of matter.
Immanuel Bloch studied physics at the University of Bonn in 1995, followed by a one year research visit to Stanford University. He obtained his PhD in 2000 working under Theodor W. Hänsch at the Ludwig-Maximilians University in Munich. As a junior group leader, he continued in Munich starting his work on ultracold quantum gases in optical lattices. In 2003 he moved to a full professor position in experimental physics at the University of Mainz, where he stayed until 2009. In 2008 he was appointed scientific director of the newly founded division on Quantum Many-Body Systems at the Max Planck Institute of Quantum Optics, in Garching. Since 2009 he also is chair of quantum optics at the Ludwig Maximilian University of Munich. Since 2012 he is vice-dean at the department of physics of LMU and since 2012 managing director of the Max Planck Institute of Quantum Optics.
The work of the physicist is concentrated on the investigation of quantum many-body system using ultracold atoms stored in optical lattice potentials. Among other things, he is known for the realization of a quantum phase transition from a superfluid to a Mott insulator, in which ultracold atoms were for the first time brought into the regime of strong correlations thereby allowing one to mimick the behaviour strongly correlated materials. The expeirmental ideas were based on a theoretical proposal by Peter Zoller and Ignacio Cirac. His further work includes the observation of a Tonks-Girardeau gas of strongly interacting bosons in one dimensions, the detection of collapses and revivals of the wavefunction of a Bose–Einstein condensate because of interactions, and the use of quantum noise correlations to observe Hanbury-Brown and Twiss bunching and antibunching for bosonic and fermionic atoms (simultaneously with the group of Alain Aspect). More recently, his research team was able to realize single-atom resolved imaging and addressing of ultracold atoms held in an optical lattice. Related work was carried out in the group of Markus Greiner.
Immanuel Bloch has received several awards for his achievements. In 2002 he received the Otto Hahn medal for his PhD work and subsequently in 2003 the Rudolf Kaiser Prize. In 2005 he was awarded the Gottfried Wilhelm Leibniz Prize of the German Science foundation, one of the highest science prizes in Germany. In 2005 he was presented with the International Commission of Optics Prize and in 2011 he received the EPS Prize for Fundamental Aspects of Quantum Electronics and Optics of the European Physical Society. In 2013 he was awarded the Körber European Science Prize and the International Senior BEC Award.
