Critical opalescence across the doping-driven Mott transition in optical lattices of ultracold atoms
C. Walsh, P. Sémon, G. Sordi +1 more
The authors show that critical opalescence - enhanced density fluctuations at all length scales - occurs in quantum matter, specifically in a doped Mott-insulating system that can be realized with ultracold atoms in optical lattices. These findings provide a theoretical framework and new predictions for ultracold-atom experiments. Looking for critical opalescence across the doping-driven Mott transition in ultracold systems may give insights on the origin of the pseudogap in cuprate high-temperature superconductors.
