Matter as quantum flow improves computer simulations

APA (C. Lackner) © APA (C. Lackner)

In the field of solid state physics, the quantum nature of radiation is usually ignored. However, in other subareas of physics such as quantum optics, this could lead to false or imprecise forecasts. In this case the new type of simulation method should provide assistance.  

 

Due to the fact that the number of particles quickly increases the computational work and time involved, it was common practice up until now to describe such systems as charged liquids. “We have now succeeded in expanding this approach by the quantization of the radiation”, explained Michael Ruggenthaler of the Institute for Theoretical Physics at the University of Innsbruck. “We now consider matter to be a type of quantum liquid whose flow properties are influenced by the photons.”

The advantage of the new method is that it is scalable upwards. It should also function in the case of more complex systems with a larger number of particles. In particular, the researchers are focused on the simulation of so-called nanoswitches i.e. individual molecules which change their electrical conductivity under irradiation. According to Ruggenthaler, the new method could also deepen our understanding of photosynthesis or can be used for the further development of photovoltaic systems.

Support measures for companies affected by COVID-19

To stimulate the economy, either new programs may be established as a result of the draft law or existing support programs (e.g. aws, ÖHT) will be expanded. All measures introduced are intended to be applicable immediately and will be in force until the end of 2020. The measures currently introduced include the following areas:
