    "abstract": "We propose a physical mechanism for tuning the atom-atom interaction strength\nat ultra-low temperatures. In the presence of a dc electric field the\ninteratomic potential is changed due to the effective dipole-dipole interaction\nbetween the polarized atoms. Detailed multi-channel scattering calculations\nreveal features never before discussed for ultra-cold atomic collisions. We\ndemonstrate that optimal control of the effective atom-atom interactions can be\nachieved under reasonable laboratory conditions. Implications of this research\non the physics of atomic Bose-Einstein condensation (BEC) and on the pursuit\nfor atomic degenerate fermion gases will be discussed.",
