Abstract:

Nuclear physics is connected to many different areas of physics, spanning arcs
from particle physics all the way to astronomy.  A solid understanding of
nuclear systems from first principles, that is, based on Quantum Chromodynamics
as the fundamental theory of the strong interaction, is therefore of great
importance, and it can only be achieved with as a concerted effort of theory and
experiment.  At the same time, fascinating universal behavior emerges that
connects low-energy few-nucleon systems to phenomena observed with trapped cold
atoms.

In this talk, I will give an overview of how modern nuclear theory can approach
these important questions with a combination of effective field theories and
tailored numerical simulations.  Particular emphasis will be placed on the
systematic construction of nuclear forces, on connecting low-energy nuclear
structure and reactions to high-energy experiments, and on recent developments
in the efficient and rigorous description of few-body resonances.  The latter
play an important role for the description of exotic states near the boundaries
of nuclear stability.
