Low-energy excitations of a boson pair in a double-well trap
arXiv:0803.2446 · doi:10.1103/PhysRevA.77.063413
Abstract
The states of a boson pair in a one-dimensional double-well potential are investigated. Properties of the ground and lowest excited states of this system are studied, including the two-particle wavefunction, momentum pair distribution and entanglement. The effects of varying both the barrier height and the effective interaction strength are investigated.
