Waves of magnetic excitation sweep through this exciting new material whether it’s in superconducting mode or not – another possible clue to how unconventional superconductors carry electric current with no loss.
Topological insulators conduct electricity on their surfaces but not through their interiors. SLAC scientists discovered that high harmonic generation produces a unique signature from the topological surface.
Spawned by the spins of electrons in magnetic materials, these tiny whirlpools behave like independent particles and could be the future of computing. Experiments with SLAC’s X-ray laser are revealing their secrets.
