A fundamental goal in nuclear theory is to obtain an ab initio
description of the nucleus -- that is, to understand the strongly
correlated motion of nucleons within the nucleus directly from the
underlying interactions of these constituents. Particularly
intriguing is the question of how simple excitation patterns,
indicating the presence of collective modes, arise out of the complex
interactions within the nuclear many-body system. The emergence of
rotational bands has recently been observed in ab initio no-core
configuration interaction calculations of light nuclei. The results
demonstrate the possibility of well-developed rotational structure in
such calculations, using realistic nucleon-nucleon interactions, and
within finite, computationally-accessible configuration spaces. This
seminar will focus on results for rotation in the Be isotopes, as well
as on the challenges of obtaining converged results for observables
relevant to rotation.
