UI group creates a disordered insulator in an optical lattice | Engineering at Illinois

UI group creates a disordered insulator in an optical lattice | Engineering at Illinois: "This approach—using one quantum system that we can control to elucidate another system that is beyond microscopic control—is called ‘quantum simulation’ and goes back to an idea first proposed by Richard Feynman in 1962.

“The microscopic effects of lattice defects and long-range electronic interactions, for example, are not well controlled in strongly correlated materials, and sophisticated theoretical approaches have reached inconsistent conclusions,” said DeMarco. “Simulating the impact of these effects on strongly correlated materials above absolute zero temperature is beyond the capabilities of even today’s supercomputers.”"
