Electric dipoles vs. magnetic dipoles —For two molecules in a harmonic trap

Abstract

We study energy levels of two heteronuclear molecules moving in a spherically\nsymmetric harmonic trap. A role of electric dipole interactions is compared and\ncontrasted with our earlier results (https://arxiv.org/abs/1512.00631) for two\nmagnetic dipolar atoms. We stress importance of a rotational energy with its\nvalue which is very high compared to the energy of dipolar interaction. We show\nthat dipolar forces do not play a significant role in the ground state of the\nsystem under typical experimental conditions. However, there exist excited\nstates that exhibit anticrossings similar to the ones observed for magnetic\ndipoles.\n
