Dynamical scaling in far-from-equilibrium Bose gases

Quantum turbulence (QT) is characterized by many degrees of freedom interacting non-linearly to produce disordered states in space and time. The advances in trapping, cooling, and tuning the interparticle interactions in atomic Bose-Einstein condensates (BECs) make them excellent candidates for studying QT. Much progress has been made in understanding and characterizing QT since the first observation of turbulence in a trapped BEC. A milestone was identifying a particle cascade demonstrated by a power law in the momentum distribution. However, there are some intrinsic difficulties in determining the range and exponent of the power law. Hence, other strategies are needed to overcome these issues. In this talk, I will present alternative methods to identify and characterize QT. I will devote special attention to the concept of dynamical scaling, which is responsible for the emergence of spatio-temporal universal scaling in far-from-equilibrium systems. Our results offer a promising route to investigate the complex dynamics of the quantum turbulent regime under a novel perspective connected to several far-from-equilibrium phenomena.
