Interfaces in Quantum Chiral Materials- Skyrmion-Weyl systems for efficient spin manipulation
Abstract
In the search for the next disruptive technology that requires low power consumption and efficient information processing, a single device s combination of distinct topological materials is an accessible avenue. The Weyl semimetal meets the low power requirement due to the production of topologically protected currents that originate from the relativistic momentum states. On the memory side, skyrmions are topological magnetic textures that integrate into scalable racetrack technology. To achieve this grand challenge of ultra-efficient topology-based integrated technology, we must understand how to stabilize both in a single system and discover the advanced materials that can deliver it. This AFOSR YIP will study the simultaneous stability of the two topologies in bulk and heterostructure systems and the currents allowing for efficient magnetization manipulation. We utilize a multipronged analytical and numerical approach at the microscopic to mesoscopic level to treat the relativistic momentum states with long-range magnetic textures on the same footing. The work will invigorate a new direction for combining distinct topologies.
