Research for a Novel Physical Reservoir

NIMFEIA
– Nonlinear Magnons for Reservoir Computing in Reciprocal Space –
is a collaborative research project which is funded by the European Union and brings together seven partners from four European countries to explore the potential of magnetic excitations and spintronic devices for a novel physical reservoir.

Our vision

NIMFEIA’s vision is to provide a novel hardware solution for physical reservoir computing using nanoscale magnetic elements combined with advanced spintronics technologies.

We base our approach on the disruptive idea of computing in reciprocal space, utilizing nonlinear interactions of quantized magnetic excitations.

These nonlinear interactions can be efficiently harnessed for reservoir computing tasks like pattern recognition and time series prediction with minimal pre-processing of input data.

By making use of the nonlinear interactions of different quantized magnetic excitations in individual spatially confined devices, such as a single magnetic disc, computing is done in reciprocal space without the need to transport information data in real space.

  Members of the NIMFEIA consortium are co-organizing the 853rd Wilhelm-Else-Heraeus-Seminar entitled “New Opportunities in Physics-based Computing: Magnonics, Spintronics, Photonics and Beyond”, which will take place 26–30 April 2026 at the Physikzentrum Bad Honnef, Germany. The WE-Heraeus-Seminar addresses one of the central challenges also pursued within NIMFEIA: how wave-based and nonlinear physical systems can be harnessed for energy-efficient information processing beyond conventional…
• Making magnetism dance in timeJanuary 16, 2026
  Researchers from the NIMFEIA consortium have discovered a new way to make tiny magnetic structures behave in unexpectedly rich and useful ways. The results are published in Science. Inside microscopic magnetic disks, magnetism naturally forms a vortex, a bit like a tiny whirlpool that can be seen in the top part of the image above. Normally, this…
