Atomic nuclei, the core of matter and the fuel of stars, are self-bound
collections of protons and neutrons (nucleons) that interact through forces
that have their origin in quantum chromo-dynamics. Nuclei comprise 99.9%
of all baryonic matter in the Universe. The complex nature of the nuclear
forces among protons and neutrons yields a diverse and unique variety
of nuclear phenomena, which form the basis for the experimental and theoretical
studies. Developing a comprehensive description of all nuclei, a long-standing
goal of nuclear physics, requires theoretical and experimental investigations
of rare atomic nuclei, i.e. systems with neutron-to-proton ratios larger
and smaller than those naturally occurring on earth.
scientific themes that are being addressed by nuclear physics research are captured
by four overarching questions:
The main area of
my professional activity is the theoretical description of those exotic,
short-lived nuclei that inhabit remote regions of nuclear landscape. This research invites a strong interaction between
nuclear physics, many-body-problem, and high- performance computing.
- How did visible matter come into being and how does it evolve?
- How does subatomic matter organize itself and what phenomena emerge?
- Are the fundamental interactions that are basic to the structure of matter fully understood?
- How can the knowledge and technological progress provided by nuclear physics best be used to benefit society?
Quantum Many-Body Problem
Heavy nuclei are splendid laboratories of many-body science. While the
number of degrees of freedom in heavy nuclei is large, it is still very
small compared to the number of electrons in a solid or atoms in a mole
of gas. Nevertheless, nuclei exhibit behaviors that are emergent in nature
and present in other complex systems. For instance, shell structure, symmetry
breaking phenomena, collective excitations, and superconductivity are
found in nuclei, atomic clusters, quantum dots, small metallic grains,
and trapped atom gases.
Although the interactions of nuclear physics differ from the electromagnetic
interactions that dominate chemistry, materials, and biological molecules,
the theoretical methods and many of the computational techniques to solve
the quantum many-body problems are shared. Examples are ab-initio and
configuration interaction methods, and the Density Functional Theory,
used by nuclear theorists to describe light and heavy nuclei and nucleonic
Physics of Open Systems
Today, much interest in various fields of physics is devoted to the study
of small open quantum systems, whose properties are profoundly affected
by environment, i.e., continuum of decay channels. Although every finite
fermion system has its own characteristic features, resonance phenomena
are generic; they are great interdisciplinary unifiers. In the field of
nuclear physics, the growing interest in theory of open quantum systems
is associated with experimental efforts in producing weakly bound/unbound
nuclei close to the particle drip-lines, and studying structures and reactions
with those exotic systems. In this context, the major problem for nuclear
theory is a unification of structure and reaction aspects of nuclei, that
is based on the open quantum system many-body formalism. Solution of this
challenging problem has been advanced recently through the new-generation
continuum shell model approaches, in particular the Gamow Shell Model
based on the Berggren ensemble.
Physics of FRIB
The Facility for Rare Isotope Beams will be a world-leading
laboratory for the study of nuclear structure, reactions and
astrophysics. Experiments with intense beams of rare isotopes
produced at FRIB will guide us toward a comprehensive
description of nuclei, elucidate the origin of the elements
in the cosmos, help provide an understanding of matter in
neutron stars and establish the scientific foundation for
innovative applications of nuclear science to society. FRIB will
be essential for gaining access to key regions of the nuclear
chart, where the measured nuclear properties will challenge
established concepts, and highlight shortcomings and needed
modifications to current theory. Conversely, nuclear theory
will play a critical role in providing the intellectual framework
for the science at FRIB, and will provide invaluable guidance
to FRIB’s experimental programs.
