Phys.Org (March 14) -- One of the grandest and most impactful frontiers of physics is the quantum many-particle problem. Scientists today still don’t well understand what happens when many quantum particles—like electrons, protons, and neutrons—come together and interact with each other. Now, two teams at the University of Illinois at Urbana Champaign, working together and attacking the problem from different physics disciplines, have shed new light on our understanding of disordered quantum materials.
