Abstract

We study internal Josephson effects in spin-1 Bose–Einstein condensates with magnetic dipole–dipole interactions by calculating the Gross–Pitaevskii equations with single mode approximations. The effects represent various oscillating modes given by combinations of 0, π, and running phase modes in Josephson effects in Bose gasses. Especially, we investigate the dependences of a magnetic field on the effects, presenting new dynamics which is not shown elsewhere.
