Researchers from the Physical Chemistry Department at the Fritz Haber Institute have together with other European research institutions and companies formed the research consortium OPTOlogic. It aims to develop optical topological computing as a means to reduce energy consumption of electronic circuits. The EU funds the project with almost 4 Million Euros.
About 10% of the world’s electricity production is used to power the information and communication technologies used for data networks, computing centres and personal digital devices. As this area is expected to take an even bigger share in the future, it is important [more...]

Angle-resolved photoemission spectroscopy (ARPES) is the most direct technique to probe the electronic structure of crystalline solids. While ARPES is typically used to map the bands’ dispersion, increasing the dimensionality of the measurements, and thus of the observables, have been shown to provide more subtle information about the electronic wavefunction of solids. In this joint experimental and theoretical work (in collaboration with J. Braun, H. Ebert, K. Hricovini, J. Minar and M. Schüler), [more...]
