Josephson oscillations in split one-dimensional Bose gases

Josephson oscillations in split one-dimensional Bose gases

We consider the non-equilibrium dynamics of a weakly interacting Bose gas tightly confined to a highly elongated double well potential. We use a self-consistent time-dependent Hartree–Fock approximation in combination with a projection of the full three-dimensional theory to several coupled one-dime...
