    "abstract": "We demonstrate the possibility of energy-selective removal of cold atoms from\na tight optical trap by means of parametric excitation of the trap vibrational\nmodes. Taking advantage of the anharmonicity of the trap potential, we\nselectively remove the most energetic trapped atoms or excite those at the\nbottom of the trap by tuning the parametric modulation frequency. This process,\nwhich had been previously identified as a possible source of heating, also\nappears to be a robust way for forcing evaporative cooling in anharmonic traps.",
