Prof. Garg’s current research interests include experimental investigation of compressional-mode giant resonances and exotic quantal rotation in nuclei.
Giant resonances are highly collective states of nuclear vibration. The compressional-mode giant resonances provide the only direct experimental measurement of the nuclear incompressibility, a fundamental property of nuclear matter that is crucial to understanding of a number of nuclear and astrophysical phenomena, including strength of collapse in supernovae explosions, collective-flow in high-energy heavy ion collisions, and properties of neutron stars—the “largest nuclei” that exist in nature. Prof. Garg’s group has been investigating the Isoscalar Giant Dipole Resonance, an exotic compressional-oscillation, also referred to as the “squeezing mode”.
The atomic nuclei exhibit a number of interesting and exciting phenomena at large angular momenta viz. shape transitions, quenching of superfluid behavior, order-to-chaos transitions, etc. These effects are studied through the g-ray de-excitation of the nucleus following heavy-ion reactions. In recent years, Prof. Garg’s group has investigated the exotic processes of chiral rotation (yes, the nuclei can be left- or right-handed!) and “anti-magnetic” rotation in nuclei.
