About Simons Foundation Presidential Lectures

Simons Foundation Presidential Lectures are free public colloquia centered on four main themes: Biology, Physics, Mathematics and Computer Science, and Neuroscience and Autism Science. These curated, high-level scientific talks feature leading scientists and mathematicians and are intended to foster discourse and drive discovery among the broader NYC-area research community. We invite anyone interested in the topic to join us for this weekly lecture series.

Ultracold atoms in our quantum gas microscope offer a fascinating view of the quantum world. With quantum simulations we can experimentally realize and study quantum-mechanical model systems that are otherwise extremely difficult to compute on classical computers, but highly relevant to understanding real world quantum materials.

In this talk, Markus Greiner will first explain — on an intuitive level — how scientists use ultracold atoms to build quantum systems atom-by-atom. He will then present his recent work on realizing fractional quantum Hall physics and on quantum simulations of the doped Hubbard model. Such quantum simulations are becoming the first useful applications of quantum machines.

About the Speaker

Markus Greiner, Associate Professor of Physics at Harvard University, has won a MacArthur

Greiner is the George Vasmer Leverett Professor of Physics at Harvard University, where he is also a co-director of both the Harvard-MIT Center for Ultracold Atoms and the Max Planck-Harvard Research Center for Quantum Optics.

He is a pioneer in quantum science and uses ultracold atoms in optical lattices to create highly controlled artificial many-body quantum systems. In 2003, while earning his Ph.D. in experimental physics from the Ludwig-Maximilians-Universität in Munich, Germany, he carried out the first quantum simulation. From 2003 to 2005, he completed postdoctoral research with Deborah Jin at JILA (the joint institute of the University of Colorado Boulder and the National Institute of Standards and Technology), where he realized a cold atom fermionic superfluid. In his research group at Harvard, he has developed quantum gas microscopy, enabling single atom control for quantum simulations. He is currently working on Fermi-Hubbard, Bose-Hubbard, dipolar and Rydberg array systems.
