Researchers have developed PreVAE-Turb, a novel framework for accelerating plasma turbulence simulations using pre-trained variational autoencoders (VAEs) derived from Stable Diffusion. This method employs a physics-informed loss function and convolutional LSTMs to accurately capture temporal dynamics in latent space. The framework has been successfully applied to both 2D Hasegawa-Wakatani turbulence and 3D gyrokinetic turbulence simulated by the GENE code, demonstrating significant computational speed-ups for generating thousands of time steps in seconds.
