摘要：
The presence of columnar defects (CDs) in NbSe3 is shown to induce oscillations in the nonlinear charge density wave (CDW) conductivity as a function of magnetic field, when the field is oriented parallel to the axes of the defects. The period of oscillation corresponds to a change in the magnetic field flux in each CD by an amount phi(0) = hc/2e, the superconducting flux quantum. This result is considered as the collective response of the moving CDW to Aharonov-Bohm flux trapped inside the CDs.
