Nuclear Theory
We investigate various phenomena originatingfrom the "strong interaction" that is associatedwith one of the most fundamental forces innature. Quarks and gluons interact strongly toform hadrons such as pions, nucleons, and soon, and hadrons are constituents of anymaterials we know. From the same theory ofthe strong interaction, unexpectedly amusingphysics can appear in special environments likehigh temperature, high density, or strongbackground (electromagnetic or gravitational)fields. We are pursuing novel phenomena basedon this established and yet profound theory ofthe strong interaction.
