John von Neumann was one of the most important mathematicians and computer pioneers of the 20th century – and an ETH alumnus. He began his studies in chemistry here one hundred years ago. ETH Professor Benjamin Sudakov pays tribute to a mathematical legacy at a symposium.
At its meeting of 24 and 25 May 2023 and upon application of Joël Mesot, President of ETH Zurich, the ETH Board appointed nine professors and awarded the title of professor twice. At the same time, the Board also bid farewell to nine professors and thanked them for their service.
ETH Zurich researchers have succeeded in demonstrating that quantum mechanical objects that are far apart can be much more strongly correlated with each other than is possible in conventional systems. For this experiment, they used superconducting circuits for the first time.
Absorption of light adds energy to a material. The electrons inside the material can react collectively or independently to that energy. Here, the dominant reaction pattern should not depend on perspective. However, in compound semiconductors, surprisingly, divergent responses are obtained depending on which atomic constituent is consulted. Knowledge of both perspectives is necessary to optimize new materials for applications in electronics and optoelectronics.
