    "abstract": "We investigate how the Unitary Correlation Operator Method (UCOM), developed\nto explicitly describe the strong short-range central and tensor correlations\npresent in the nuclear many-body system, relates to the Similarity\nRenormalization Group (SRG), a method to band-diagonalize Hamiltonians by\ncontinuous unitary transformations. We demonstrate how the structure of the\nUCOM transformation, originally motivated from the physically intuitive picture\nof correlations in coordinate space, arises naturally from the SRG flow\nequation. Apart from formal considerations we show that the momentum space\nmatrix elements of the effective interactions obtained in both schemes agree\nextremely well.",
