Graph showing match of expimental data for out-of-equilibrium one-dimensional gases with theory

New experiments using trapped one-dimensional quantum gases fit with the predictions of the recently developed theory of generalized hydrodynamics. Graph showing the time evolution of the quasiparticle momentum distribution—a property of the atoms in the gases—in a bundle of one-dimensional gases. The experimental data (red lines) nearly perfectly match the predictions of generalized hydrodynamics theory (blue lines).
