Highly efficient optimization mesh movement method based on proper orthogonal decomposition [PDF]
International Journal for Numerical Methods in Engineering, 2010 AbstractIn this paper, we implement the method of proper orthogonal decomposition (POD) to generate a reduced order model (ROM) of an optimization‐based mesh movement scheme. In this study it is shown that POD can be used effectively to generate an ROM, that accurately reproduces the full order mesh movement algorithm, with a decrease in computational ...

Néel Tensor Torque in Polycrystalline Antiferromagnets
Advanced Materials, EarlyView.This work introduces a Néel tensor torque based on a rank‐two symmetric tensor capturing spin correlations in a polycrystalline antiferromagnet. It shows the Néel tensor can be shaped and reshaped through the spin‐orbit torque (SOT) technique, enabling field‐free SOT switching with a specific polarity of the adjacent ferromagnet. This discovery opens a
