Let me give you a glimpse at my research. I uploaded a video of my latest simulation on youtube, . You can see the formation and evolution of vortices in hot plasma such as fusion plasma. The subtlety is that these vortices do not live in the real, everyday-life 3D space, but in an imaginary, mathematical 6D space. They do impact 3D space though. To be more precise, this video shows the nonlinear growth, evolution and interaction of self-coherent phase-space structures in a numerical simulation of ion-acoustic turbulence (actually 1D with periodic boundary conditions, or 2D in phase-space). The turbulence grows in contradiction with linear theory, which predicts that all waves are stable in this system. In other words, this is a subcritical instability. Up-left and up-center: perturbed distribution function of ions and electrons. Bottom-left: spatially-averaged velocity distribution. Bottom-center, spatially-averaged perturbed velocity distribution. Bottom-right: electric field spectrum. Top-right: time-evolution of the field energy, with an horizontal line to indicate the instant of each frame. During this simulation, several vortices form spontaneously and interact with each others. This process is associated with a significant redistribution of the electrons, anomalous resistivity and turbulent heating. Please ask me any question or clarification. It's a very good exercise for me explain my research to laypeople.
