| 内容記述 | We numerically investigate the spatiotemporal dynamics of a circular flow mode in a ring array of Bose- Einstein condensates, which consists of M identical Bose-Einstein condensates that couple to the nearestneighbor sites by tunneling. Introducing a rotational potential in the Gross-Pitaevskii equation, a series of circular flow modes is resonantly excited. For the initial conditions with uniform density and one-round phase difference of 2p, sl=0,1, . . . ,M−1d, two circular flow modes are excited for each circulation-quantized number l. It is shown that these circular flow modes periodically appear in time in the presence of the rotational field and persistently survive with a constant shape even after the external potential is removed, the transitions between the circular flow modes with different quantized number l can be realized by applying the phaseimprinting optical pulses, and the rotational velocity of the circular flow mode can be continuously modulated by adiabatically tuning the scattering length in a magnetic field, i.e., by use of the Feshbach resonance. |
