Dr. Markus Greiner

Biography

Markus Greiner is the George Vasmer Leverett Professor at Harvard University in the Department of Physics. His research focuses on experiments with ultracold atoms and strongly correlated many-body quantum systems that are experimentally realizable in a well-controlled manner. This work opens the door to studying fundamental questions in modern condensed matter physics, quantum information, and atomic physics. His achievements include loading ultracold atoms into optical lattice potentials and achieving significant observations such as the quantum phase transition between superfluid and Mott insulator states. He has created highly entangled states in optical lattices through techniques like photoassociation of molecules. Collaborating with colleagues in Colorado, he has observed fermionic atoms that lead to a condensate of generalized Cooper pairs in the BCS-BEC crossover regime. At Harvard, Professor Greiner is pioneering research on accessible quantum systems, utilizing both bosonic and fermionic atoms in optical lattices, while developing innovative quantum gas microscopy techniques. His experiments enable the realization of novel strongly correlated quantum states that can be studied with unprecedented control.
