Controlled direct acceleration of electrons in very strong laser fields can offer a path towards ultra-compact accelerators. Such a direct acceleration requires rectification and decoupling of the ...

Theories that attempt to explain the relativistic jets suggest that the magnetic field in the vicinity of the black hole is incredibly twisted by the dynamics of the black hole's warping of space ...

Physicists in Japan and Taiwan have developed a compact, highly efficient method of generating high-energy ion beams by firing a laser pulse at a target made from two layers of graphene. Led by ...
