Extreme Plasmons (Adv. Quantum Technol. 6/2025)

Abstract

The cover picture shows a model of nonperturbative oscillations of quantum electron gas, collisionlessly excited by an ultraintense, ultrashort electron beam propagating in a conductive tube. These large-amplitude, coherent oscillations of conduction electron gas can uncover access to unprecedented PetaVolts per meter fields which open new possibilities that include gamma-ray lasers and particle colliders on a chip.
