Physics

Just as electrons flow through an electrical conductor, magnetic excitations can travel through certain materials. Such excitations, known in physics as "magnons" in analogy to the electron, could transport information much more easily than electrical conductors. An international research team has now made an important discovery on the road to such components, which could be highly energy-efficient and considerably smaller.

Scientists at EPFL’s Swiss Plasma Center and DeepMind have jointly developed a new method for controlling plasma configurations for use in nuclear fusion research.

At EPFL, a team of scientists created and observed a new physical phenomenon on an optical chip using modified lights.

Scientists in Switzerland and Germany have achieved efficient electron-beam modulation using integrated photonics – circuits that guide light on a chip. The experiments could lead to entirely new quantum measurement schemes in electron microscopy.

The launch of the James Webb Space Telescope is set to take place in the coming days. For ETH Zurich physicist Adrian Glauser, who was involved in two unspectacular but vital contributions to this ambitious project, it will bring to an end a long period of anxious anticipation.
