Noise – not a nuisance but a source of information

Researchers at the University of Konstanz discover a new type of ultrafast magnetic switching by investigating fluctuations that normally tend to interfere with experiments as noise.

Noise on the radio when reception is poor is a typical example of how fluctuations mask a physical signal. In fact, such interference or noise occurs in every physical measurement in addition to the actual signal. "Even in the loneliest place in the universe, where there should be nothing at all, there are still fluctuations of the electromagnetic field", says physicist Ulrich Nowak. In the Collaborative Research Centre (CRC) 1432 "Fluctuations and Nonlinearities in Classical and Quantum Matter beyond Equilibrium" at the University of Konstanz, researchers do not see this omnipresent noise as a disturbing factor that needs to be eliminated as far as possible, but as a source of information that tells us something about the signal.

Magnetic whirls pave the way for energy-efficient computing

International research collaboration involving the University of the Konstanz has been able to increase the diffusion of magnetic whirls – the skyrmions – by a factor of ten.
In today's world, our lives are unimaginable without computers. Up until now, these devices process information using primarily electrons as charge carriers, with the components themselves heating up significantly in the process. As a result, active cooling is required, which comes with high energy costs. Spintronics aims to solve this problem: Instead of utilizing the electron flow for information processing, it relies on their spin – their intrinsic angular momentum. This approach is expected to have a positive impact on the size, speed and sustainability of computers.
