Nuclear Structure in the Framework of the Unitary Correlation Operator Method

Understand

Correlations play a crucial role in the nuclear many-body problem.

• We give an overview of recent developments in nuclear structure theory aiming at the description of these interaction-induced correlations by unitary transformations.
• We focus on the Unitary Correlation Operator Method (UCOM), which offers a very intuitive, universal and robust approach for the treatment of short-range correlations.
• We discuss the UCOM formalism in detail and highlight the connections to other methods for the description of short-range correlations and the construction of effective interactions.
