    "abstract": "We here develop a theory on optical absorption in a dilute Bose gas at low\ntemperatures. This theory is motivated by the Bogoliubov theory of elementary\nexcitations for this system, and takes into account explicitly the modification\nof the nature and dispersion of elementary excitations due to Bose-Einstein\ncondensation. Our results show important differences from existing theories.",
