Landau levels analog to electric dipole

In this Letter we study the quantum dynamics of a neutral particle in the presence of an external magnetic field. We demonstrate in a specific field-dipole configuration that we have a quantization similar to the Landau levels. We investigate this quantization motivated by the recent analysis of Landau-Aharonov-Casher (LAC) quantization of Ericsson and Sjöqvist [M. Ericsson, E. Sjöqvist, Phys. Rev. A 65 (2001) 013607]. The energy eigenfunction and eigenvalues are obtained.
