Benchmarks of generalized hydrodynamics for one-dimensional Bose gases by R. S. Watson, S. A. Simmons, K. V. Kheruntsyan

“…For low temperatures and weak interactions, we highlight situations where GHD, while not capturing interference phenomena on short lengthscales, can describe a coarse-grained behavior based on convolution averaging that mimics finite imaging resolution in ultracold atom experiments. In a quantum Newton's cradle setup based on a double-well to a single-well trap quench, we find that GHD with diffusive corrections demonstrates excellent agreement with the predictions of a classical field approach.…”

Bose-Hubbard physics in synthetic dimensions from interaction Trotterization by L. Barbiero, L. Chomaz, S. Nascimbene, N. Goldman

“…Activating transitions between a set of atomic internal states has emerged as an elegant scheme by which lattice models can be designed in ultracold atomic gases. In this approach, the internal states can be viewed as fictitious lattice sites defined along a synthetic dimension, hence offering a powerful method by which the spatial dimensionality of the system can be extended. …”
