Huygens Colloquium: Johan Mentink

Challenging the Limits of Magnetism – Insights from Theory and Simulations

Magnetism is known since ancient times. However, ultrafast nanomagnetism, defined by the dynamics of microscopic spins operating at the fundamental length and timescale of the quantum mechanical exchange interaction, is only recently becoming accessible.

In my research we approach ultrafast nanomagnetism from the side of theory and simulations. I will review recent results obtained with atomistic and quantum simulations of magnetism, that were conducted in close interaction with experimentalists. We show that both classical and quantum fluctuations, normally considered a nuisance yet inevitable at short length and time scales, can challenge the limits for the fastest motion of spins in magnetic materials.

Furthermore, I will outline how this research field can further advance by interdisciplinary research on neuromorphic hardware. This hardware has a radically different architecture, which for specific tasks can be both faster and more energy efficient than traditional hardware. Deployment of neuromorphic hardware may therefore allow breaking existing computational barriers, with potentially high impact for the development of green information technology.

Huygens Colloquia

In the Faculty of Science a great diversity of exciting research is going on. After some years of silence – due to the Covid-lockdowns – the Huygens Colloquia are back to present research highlights to a wider audience. 

The Huygens Colloquia are a colloquium series by Faculty of Science employees for all faculty employees and students. Every month, a colleague will discuss their science and their latest results in an accessible way. Access is free and no registration is needed. Bring your own lunch, coffee, and tea will be provided.
