Blume}, title = {Pseudopotential treatment of two aligned dipoles under external harmonic confinement}, abstract = {Dipolar Bose and Fermi gases, which are currently being studied extensively experimentally and theoretically, interact through anisotropic, long-range potentials. Here, we replace the long-range potential by a zero-range pseudopotential that simplifies the theoretical treatment of two dipolar particles in a harmonic trap. Our zero-range pseudopotential description reproduces the energy spectrum of two dipoles interacting through a shape-dependent potential under external confinement very well, provided that sufficiently many partial waves are included, and readily leads to a classification scheme of the energy spectrum in terms of approximate angular momentum quantum numbers. The results may be directly relevant to the physics of dipolar gases loaded into optical lattices. }, year = {2007}, journal = {Physical Review A}, volume = {75}, pages = {052705}, month = {2007-05}, issn = {1050-2947}, doi = {10.1103/PhysRevA.75.052705}, }
