Quantum Theory Explains LNL Conductivity Oscillations

Researchers propose a quantum mechanical theory for the Lee-Naughton-Lebed (LNL) angular oscillations in moderately strong electric fields, expanding on Kobayashi et al.'s findings in $\alpha$-(ET)2-based organic conductors. The study introduces Equation (25) to describe the splitting of LNL conductivity maxima, demonstrating its validity for lower voltages and its general applicability to quasi-one-dimensional conductors.
