Quantifying resonant and near-resonant interactions in rotating turbulence
(Cambridge University Press, 2016-11)
Nonlinear triadic interactions are at the heart of our understanding of turbulence. In flows where waves are present, modes must not only be in a triad to interact, but their frequencies must also satisfy an extra condition: ...
Temporal correlations imaging fixed targets through turbulence
(Optical Society of America, 2016-06)
We study the temporal correlations from dynamic imaging through turbulence using incoherent light from fixed highcontrast targets. We conduct our experiment in controlled laboratory conditions using several values of the ...
Incompressible energy spectrum in atomic Bose-Einstein condensates: a weak wave turbulence theory approach
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2022-08-25)
Bose-Einstein condensates with their superfluidity property provide an interesting parallel to classical fluids. Due to the Kolmogorov spectrum of homogeneous turbulence the statistics of the incompressible velocity field ...
Effects of the background turbulence on the relaxation of ion temperature anisotropy in space plasmas
(Frontiers Media, 2021)
Turbulence in space plasmas usually exhibits two regimes separated by a spectral break that divides the so called inertial and kinetic ranges. Large scale magnetic fluctuations are dominated by non-linear MHD wave-wave ...
Wave turbulence buildup in a vibrating plate
(Springer, 2015-10)
We report experimental and numerical results on the buildup of the energy spectrum in wave turbulence of a vibrating thin elastic plate. Three steps are observed: first a short linear stage, then the turbulent spectrum is ...

Statistics of magnetic reconnection in two-dimensional magnetohydrodynamic turbulence
(American Institute of Physics, 2010-03)
The nonlinear dynamics of magnetic reconnection in turbulence is investigated through direct numerical simulations of decaying, incompressible, two-dimensional magnetohydrodynamics. Recently, it was shown by Servidio [Phys. ...
