Comparing many-body approaches against the helium atom exact solution by Jing Li, N. D. Drummond, Peter Schuck, Valerio Olevano

“…Over time, many different theories and approaches have been developed to tackle the many-body problem in quantum chemistry, condensed-matter physics, and nuclear physics. Here we use the helium atom, a real system rather than a model, and we use the exact solution of its Schr\"odinger equation as a benchmark for comparison between methods. …”

Two-dimensional Brownian motion of active particle on superfluid helium surface by Roman E. Boltnev, Mikhail M. Vasiliev, Oleg F. Petrov

“…Abstract We report an experimental study of the 2D dynamics of active particles driven by quantum vortices on the free surface of superfluid helium at T = 1.45 К. The particle motion at short times (< 25 ms) relates to anomalous diffusion mode typical for active particles, while for longer times it corresponds to normal diffusion mode. …”
