Pictured is the plasma turbulence generated when two plasma beams fly through one another at high velocities. Similar to most chaotic systems, this phenomenon leads to the growth of entropy. However, unlike conventional systems, a collisionless plasma inherits conservation laws from its previously ordered state.

💥 New paper out in Science Advances! We show that radiatively cooled relativistic plasmas can spontaneously emit coherent, polarized radiation via a maser instability. Work with @thales-silva.bsky.social and @luisoliveiraesilva.bsky.social . 🔗 www.science.org/doi/10.1126/...
