M. Purcell and P. F. Barker<br/>We report on the ability to tailor the optical dipole force for molecules by tuning their effective polarizability with strong field alignment using polarized fields. We have measured a difference of 20% in the dipole force on cold CS_{2} molecules when changing from linear to near-circular polariza...<br/><img src="http://prola.aps.org/graphics/prlsugg30x30.gif" width="30" height="30" alt="PRL Editors' Suggestion"/><br/>[Phys.
