Tilman peacock

from Wikipedia, the free encyclopedia

Tilman Pfau (born July 25, 1965 in Bad Cannstatt ) is a German physicist.

Life

Pfau began to study physics at the University of Konstanz in 1986 , received his diploma in 1992 and did his doctorate there in 1994 with Jürgen Mlynek . He then worked as a visiting researcher at the ENS in Paris with Claude Cohen-Tannoudji and at the MIT with Wolfgang Ketterle . In 1998 he completed his habilitation in Konstanz on the subject of "Light in Atomic Optics". Since 2000 he has been a professor at the University of Stuttgart , where he heads the 5th Physics Institute. Since then he has held visiting professorships in Helsinki, Beijing, Toronto and Cambridge.

In 2010 he was elected a Fellow of the American Association for the Advancement of Science and in 2014 he became a Fellow of the American Physical Society . In 2011 he was awarded an Advanced Investigator Grant from the European Research Council and in 2014 the Gentner-Kastler Prize of the Société Française de Physique and the DPG. In 2017 he received the Herbert P. Broida Prize . He is co-founder and director of the Center for Integrated Quantum Science and Technology IQST. He headed a special research area (SFB / TR21) for 12 years and is the spokesperson for a DFG priority program (SPP1929).

research

Pfau is engaged in experimental research in the field of ultra-cold quantum gases with strong dipole-dipole interactions. These include magnetic dipolar gases as well as Rydberg gases. In 2005 his research group succeeded in the Bose-Einstein condensation of chromium atoms and thus for the first time a Bose-Einstein condensate with a strong dipolar interaction (due to the large magnetic moment of the chromium atoms). In 2009 he and his team were able to demonstrate a new type of molecular bond for the first time, the so-called " trilobite molecules", which are formed from a Rydberg atom and a ground state atom and have extremely large distances between the two nuclei and an electron density distribution reminiscent of the namesake. In 2019, his research group demonstrated a suprasolid state , including the corresponding Goldstone mode as a collective stimulus.
