Impact of DMI on magnonic antiferromagnetic leaky integrate-and-fire neuronal networks — •Verena Brehm and Alireza Qaiumzadeh — QuSpin, NTNU Trondheim, Norway

Two shifts of paradigms promise to revolutionize modern day computation: First, neuromorphic computing aims to mimic the human brain, which is a fundamentally different approach compared to the state-of-the-art von Neuman computing architecture. Second, antiferromagnetic magnonics promises to be faster and more energy-efficient compared to conventional electronics through avoidance of Joule heating and high-frequency eigenexcitations. We combine both fields and study a proof-of-principle antiferromagnetic spiking neural network, more specifically a leaky integrate-and-fire model both analytically and numerically [1,2].
