Explainable AI-Based Physical Theory for Advanced Materials Design
Researchers establish an “prolonged Landau free energy design” for causal analysis and visualization in nano-magnetic devices with AI and topology.
Microscopic materials analysis is vital to attain desirable performance in next-generation nanoelectronic devices, such as low power usage and high speeds. However, the magnetic products involved in such gadgets often display exceptionally complex interactions between nanostructures and magnetic domains. This, in turn, makes functional style challenging.
Traditionally, researchers have performed a visual analysis of the microscopic image information. This often makes the interpretation of such information extremely subjective and qualitative. What is lacking is a causal analysis of the systems underlying the complicated interactions in nanoscale magnetic materials.

This was accomplished using an “prolonged Landau complimentary energy design” that the team established using a mix of topology, data science, and free energy. The model could show the physical system as well as the important area of the magnetic effect, and proposed an optimum structure for a nano gadget. The design utilized physics-based features to draw energy landscapes in the information space, which could be used to comprehend the complex interactions at the nanoscales in a broad range of materials.
” Conventional analysis are based on a visual examination of microscopic lense images, and the relationships with the material function are expressed only qualitatively, which is a significant bottleneck for material style. Our extended Landau complimentary energy design allows us to identify the physical origin and area of the complex phenomena within these products.
