摘      要：We investigate the cyclotron dynamics of Bose-Einstein condensate(BEC)in a quadruple-well potential with synthetic gauge *** use laser-assisted tunneling to generate large tunable effective magnetic fields for *** mean position of BEC follows an orbit that simulated the cyclotron orbits of charged particles in a magnetic *** the absence of atomic interaction,atom dynamics may exhibit periodic or quasi-periodic cyclotron *** the presence of atomic interaction,the system may exhibit self-trapping,which depends on synthetic gauge fields and atomic interaction *** particular,the competition between synthetic gauge fields and atomic interaction leads to the generation of several discontinuous parameter windows for the transition to self-trapping,which is obviously different from that without synthetic gauge fields.
