In combined theoretical and experimental work, ETH physicists introduce and demonstrate a novel mechanism for electron optics in two-dimensional solid-state systems. The discovery opens up a route to engineering quantum-optical phenomena in a variety of materials and devices.

In the current round of appointments, four men and four women were appointed or promoted to ETH professors, among them the physicist Anna Sótér, who has been appointed Tenure Track Assistant Professor of Low Energy Particle Physics.

In 2019, the Major Atmospheric Gamma Imaging Cherenkov (MAGIC) telescopes — to which ETH physicists have made substantial contributions — detected the first Gamma Ray Burst at very high energies. With further analyses of those data, the MAGIC scientists now confirmed that the speed of light is constant in vacuum, and not dependent on energy. So, like many other tests, GRB data also corroborate Einstein’s theory of General Relativity.
