Quantum Transport Patterns Revealed in Helical Lattice Structures Through Localization and Current Analysis

Scientists have mapped how magnetic fluxes and disorder influence electron behavior in helical quantum systems. The study reveals distinct transport regimes through localization metrics and persistent current patterns.

Localization Dynamics in Quantum Systems

Recent research published in Scientific Reports has uncovered detailed patterns of electron localization and persistent currents in quasiperiodic disordered helical lattices. According to the report, these many-body currents quantify how the filled Fermi sea responds to variations in magnetic fluxes, providing complementary transport diagnostics alongside single-particle localization measures. The study reportedly examines how hopping anisotropy, disorder strength, and applied magnetic flux interact across conducting and insulating regimes.
