Research Interests

Theoretical Nuclear Physics and Nuclear Astrophysics Among the primary goals of nuclear physics are: (1) Understanding many-body hadronic phenomena in terms of fundamental constituents and their interactions; (2) Extracting information on the elementary processes using nuclei as natural laboratories. As the meaning of "fundamental" and "elementary" changes, the domain and methodology of nuclear physics are steadily expanding. I list below two of my recent main research areas. Effective Field Theory Approach to Nuclear Physics --- With the advent of quantum chromodynamics (QCD) as a fundamental theory of strong interactions, a big challenge is to make connection between nuclear phenomena and QCD. Effective field theory provides a powerful tool for tackling this problem; in particular, nuclear chiral perturbation theory has been revealing many interesting consequences of chiral symmetry for low-energy nuclear phenomena. Our work in this domain is primarily concerned with: (i) Nuclear exchange currents; (ii) Ab initio calculations of electroweak processes in few-body systems; (iii) Extension of nuclear chiral perturbation theory to higher energy-momentum transfer regimes. Nuclear Astrophysics --- Astrophysical processes often depend on the behavior of nuclear systems under extreme conditions (ultra-high temperature, ultra-high pressure, etc.). We have been trying to deepen our understanding of these exotic systems; for instance, we are studying the possibility of strangeness condensation in a dense medium and its consequences in astrophysical phenomena and heavy-ion collisions. In neutrino astrophysics reliable estimates of neutrino-nucleus reaction cross sections are crucially important. Our group has been actively engaged in theoretical studies of these reactions.
