Figure 1:
(a) Real-space and (b) momentum density distributions for a spin-orbit-coupled gas of bosons in a chaotic regime. In the experiment theorized by Larson et al. [1], such wave function distributions are calculated for a system that has thermalized after an initial perturbation brought it to an excited state. The high-density regions correspond to so-called “quantum scars,” signatures of quantum chaos that are remnants of classic periodic orbits.
