We discovered a new way to generate spin-orbit coupling dynamically in nonrelativistic materials. This finding opens new avenues for tuning material properties and advancing spintronics device applications.

Area of Science:

  • Condensed Matter Physics
  • Materials Science
  • Quantum Mechanics

Background:

  • Spin-orbit coupling is essential for solid-state properties and spintronics.
  • Current spin-orbit coupling originates from relativistic effects and is a single-particle band phenomenon.

Purpose of the Study:

  • To propose and investigate a novel mechanism for generating spin-orbit coupling dynamically.
  • To explore its emergence in strongly correlated, nonrelativistic systems.

Main Methods:

  • Investigating Fermi surface instabilities in higher angular momentum channels.
  • Theoretical modeling of strongly correlated, nonrelativistic systems.

Main Results:

  • A new mechanism for dynamic spin-orbit coupling generation is proposed.
