Computational Magnetic Metamaterial
Computational Magnetic Metamaterials
COMET is an interdisciplinary research initiative exploring the intersection between computer architecture and nanomagnetism. The key focus of COMET is to discover new concepts for ultra-low-power computing systems based on emergent physical phenomena. Magnetic metamaterials have great potential as massively-parallel computing substrates, offering inherent energy efficiency and direct tunability at the nanoscale.
Within COMET, we investigate the computational potential of coupled nanomagnetic systems. The work spans from simulations using NTNU's GPU compute cluster to fabrication at NTNU NanoLab and real world measurements in our own laboratories as well as at international synchrotron facilities.
flatspin is a novel simulator for systems of interacting mesoscopic spins on a lattice, also known as artificial spin ice (ASI). Through GPU acceleration, flatspin can simulate the dynamics of millions of magnets within practical time frames, enabling exploration of large-scale emergent phenomena at unprecedented speeds.
