In classical physics, a vacuum is a total void—a true manifestation of nothingness. But quantum physics says that empty space isn’t really empty. Instead, it’s buzzing with “virtual” particles ...

Zoltan Fodor receives funding from DFG, BMBF. When the results of an experiment don’t match predictions made by the best theory of the day, something is off. Fifteen years ago, physicists at ...

Addition of iridium leads to increased electron localization and stronger spin-orbit coupling between 3d electrons of iron and cobalt and 5d electrons of iridium, significantly enhancing the magnetic ...

In the moiré material produced at ETH, the electron spins are disordered if there is exactly one electron per lattice site (left). As soon as there are more electrons than lattice sites (right) and ...

Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is ...
