What to know about Imaginary-time technique speeds X-ray scattering simulations by 50-fold for extreme matter

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf have developed a mathematical transformation using imaginary-time techniques to accelerate X-ray scattering simulations by up to 50-fold. This method improves the analysis of matter under extreme conditions, with potential applications in fusion research and laboratory astrophysics.
