抄録	We report evidence for Aharonov-Bohm (AB) oscillations with temporal current switching at 5.1 and 79K by using charge-density wave (CDW) loops in TaS3 ring crystals. The periodicity of the AB oscillations is h/2e, and this is confirmed by employing four samples with different diameters. This means that sliding CDWs carry 2e charge quanta. We observe current switching between the two states, namely the high and low urrent states, as a result of the separation of field-dependent and time-dependent fluctuations. The probability distribution of the switching oscillates also with a period of h/2e. We discover that the bserved oscillations, which are a superposition of the current fluctuations and the switching behavior, have a period h/2e.
