Fragmented Many-Body Ground States for Scalar Bosons in a Single Trap
Fragmented Many-Body Ground States for Scalar Bosons in a Single Trap
We investigate whether the many-body ground states of bosons in a generalized two-mode model with localized inhomogeneous single-particle orbitals and anisotropic long-range interactions (e.g., dipole-dipole interactions) are coherent or fragmented. It is demonstrated that fragmentation can take place in a single trap for positive values of the interaction couplings, implying …
