摘要

We discuss the effect of Aharonov-Bohm magnetic flux on the time reversal symmetric properties of .mesoscopic metallic ring systems. It is usually believed that AB flux causes time reversal symmetry breaking. We analyse the case of mesoscopic persistent currents and find out that AB flux does not breai time reversal symmetry. Our arguments are supported by the general theory of mesoscopic persistent currents.
