Techniques to measure quantum criticality in cold atoms
Kaden R. A. Hazzard, Erich J. Mueller
We describe how rescaling experimental data obtained from cold atom density profiles can reveal signatures of quantum criticality. We identify a number of important questions which can be answered by analyzing experimental data in this manner. We show that such experiments can distinguish different universality classes and that the signatures are robust against temperature, noise, and finite system size.
