A system of two dipolar particles that are confined in a double‐well potential and interact via a realistic isotropic interaction potential is investigated as a protoype for ultracold atoms with a magnetic dipole moment or ultracold dipolar heteronuclear diatomic molecules in double‐well traps or in optical lattices. The resulting energy spectrum is discussed as a function of the dipole–dipole interaction strength. The variation of the strength of the dipole–dipole interaction is found to lead to various resonance phenomena. Among those are the previously discussed inelastic confinement‐induced resonances as well as the dipole‐induced resonances. It is found that the double‐well potential gives rise to a new type of resonances, tunnel‐induced dipolar ones.
