A universal Doppler effect limits the maximal spin current in magnetic insulators which have been driven out of equilibrium by magnetic fields. These findings by an international research team present a surprising parallel to what happens in superconductors driven by electric fields and could aid the design of future nano-devices. more

Researchers gain a direct view of spin waves by placing a diamond chip with a layer of nitrogen vacancy centers on top of a thin magnetic film. Once the spin waves are excited, the NV centers pick up their magnetic fields and enable high-resolution imaging. more

Researchers show that short-lived topological states can be tracked with equally short light flashes spiraling like a corkscrew, using signal difference between left- and right-handed light. more

Researchers at the University of Oxford and the MPSD report in Physical Review Letters that a dynamical version of superconductivity, which is generated by periodically shaking the material, is intimately tied to strong electronic correlations and geometric frustration. more

Laser light with a broad colour spectrum turns the insulating quasi two-dimensional material La2CuO4 (LCO) into a three-dimensional metal. The research, now published in PNAS, reveals that specific vibrations of the crystal lattice are involved in this metallization process. more
