Determination of the Fine Structure Constant Based on the Quantum Hall Effect

概要

論文の詳細を見る
The quantum Hall effect has attracted a great deal of attention because it provides a new method for high precision determination of the fine structure constant α. At present, the most accurate value of α is that derived from the experiment of anomalous magnetic moment of electron using the QED theory. Whether or not the value of α determined from the quantum Hall effect is identical with that determined by using the QED theory and the experimental result which is independent of the electrical units, is one of the most interesting problems which might affect the fundamental framework of physics. During the course of every effort toward solving this problem, resistance standards also are to be subjected to a severe examination.
