Characteristic Length Scale during the Time Evolution of a Turbulent Bose-Einstein Condensate. Madeira, L., García-Orozco, A. D., Moreno-Armijos, M. A., dos Santos, F. E. A., & Bagnato, V. S. Symmetry, 13(10):1865, October, 2021. Number: 10 Publisher: Multidisciplinary Digital Publishing InstitutePaper doi abstract bibtex Quantum turbulence is characterized by many degrees of freedom interacting non-linearly to produce disordered states, both in space and in time. In this work, we investigate the decaying regime of quantum turbulence in a trapped Bose-Einstein condensate. We present an alternative way of exploring this phenomenon by defining and computing a characteristic length scale, which possesses relevant characteristics to study the establishment of the quantum turbulent regime. We reconstruct the three-dimensional momentum distributions with the inverse Abel transform, as we have done successfully in other works. We present our analysis with both the two- and three-dimensional momentum distributions, discussing their similarities and differences. We argue that the characteristic length allows us to intuitively visualize the time evolution of the turbulent state.
