Researchers at Sun Yat-Sen University have demonstrated that off-axis electron vortices conserve orbital angular momentum through a novel SU(1,1) dynamical invariant, even in nonuniform magnetic fields lacking rotational symmetry. This finding establishes a fundamental principle for stable quantum transport mechanisms without relying on traditional centroid-frame symmetry protection. The discovery expands the theoretical framework governing electron behavior and could inform future designs of advanced spintronic devices or quantum information processors that operate under varying field conditions.
Off-Axis Vortices Retain Spin Despite Magnetic Field Shifts

Unlike on-axis counterparts, researchers found that off-axis electron vortices retain their spin—specifically, orbital angular momentum—even with magnetic field shifts.
Researchers at Sun Yat-Sen University have discovered that electrons can maintain their orbital angular momentum (OAM) even when displaced from the center of magnetic fields. The work identifies an SU(1,1) invariant that explains how…
