摘要：

The ground state phases of ultracold bosons in a ladder optical lattice subjected to a magnetic field are studied. With the inhomogeneous Gutzwiller variational method, we find that a modulated supersolid phase appears as the magnetic flux increases. The dependence of the supersolid period on the magnetic flux satisfies the commensurate conditions of integer times of 2 pi/phi.
