Areas of Interest
Dr. Ji's
research focuses on the novel and accurate theoretical predictions of
the hadron structures and spectra of ordinary, strange, charm and
beauty mesons and baryons including their exotic molecular aspects and
the role of glueball components. In order to construct a realistic
hadron model consistent with the precision experimental data envisioned
at JLAB, formerly known as CEBAF, the program emphasizes relativity by
taking advantage of the lightcone and the fundamental symmetries of C,
P, T, crossing, duality, and unitarity. The primary interest of this
program is to investigate the nonperturbative aspects of QCD field
theory represented by the vacuum condensation, relate them to the
many-body physics based on the BCS theory of superconductors, and
develop an effective field theory to describe the shell and liquid
structures of hadrons and nuclei. The perturbative QCD calculations
involve algebraic manipulation, software development and large-scale
numerical computations using local and national level supercomputers.
Dr. Ji
is currently a member of
International Light Cone Advisory Committee (ILCAC)
and has been a theory
consultant for JLAB(CEBAF)
and the Seoul National University. His research with a couple of
graduate students attracted SURA/CEBAF fellowships in recent years.
