The DeMarco group at the University of Illinois
Quantum simulation using ultracold atom gases
The DeMarco Group at the University of Illinois uses ultracold atom gases trapped in optical lattices to simulate models of strongly correlated electronic solids. We cool atom gases to temperatures just billionths of a degree above asbolute zero temperature and trap them in a crystal of light. The atoms play the role of electrons, and the light that of a crystalline matrix. This idea, called quantum simulation, was first proposed by Richard Feynman and was the original motivation for quantum computing.

The DeMarco group helped to found and regularly attends the Midwestern Cold Atom Workshop.
Data from our article on 3D Anderson localization of Ultracold Matter published in Science 344, 66 (2011) can be found here.
A MATLAB implementation of the MRAF algorithm (with example kinoforms) can be found here.
The DeMarco group has pioneered techniques for studying the impact of disorder on strongly interacting quantum systems, dynamics and out-of-equilibrium phenomena in Hubbard models, and disorder-induced quantum localization. Our signficant results include:
The first atomic realization of the disordered Bose and Fermi-Hubbard models.
The first demonstration of 3D Anderson localization of quantum matter.
The first observation of the quantum Kibble-Zurek mechanism in a quantum quench.
Fund our research
We work on one of the most exciting frontiers of 21st century physics: strongly interacting, many-particle quantum mechanics. Your financial support can contribute to expanding our understanding of the physics behind the behavior of materials with superlative properties, such as high-temperature superconductors. Enhanced knowledge of this physics may lead to the next generation of materials with primary applications to energy transmission, information processing, and thermal management. By supporting our group you can also help to develop leaders in science and engineering who will position our economy to succeed in the future.
