Nuclear Incompressibility: How Collective Excitation Modes of a Nucleus Characterize Astrophysical Processes.

Prof. Umesh Garg, University of Notre Dame
https://physics.nd.edu/people/umesh-garg/
To the students: Dr. Garg has been the director of their physics REU program for about 30 years, he will stop by the student lunge around 9:30-10am.

The Nuclear Incompressibility parameter is one of three important
components characterizing the nuclear equation of state (EOS). It has
crucial bearing on diverse nuclear and astrophysical phenomena,
including radii of neutron stars, strength of supernova collapse, emission
of neutrinos in supernova explosions, and collective flow in medium- and
high-energy nuclear collisions.  In this talk I will review current
status of the research on direct experimental determination of nuclear
incompressibility via the compressional-mode giant resonances. In particular,
measurements on a series of Tin and Cadmium isotopes have provided an
"experimental" value for the asymmetry term of nuclear incompressibility, which
can provide constraints on the EOS of neutron stars.

About the speaker:
Umesh Garg, a Professor of Physics at the University of Notre Dame, graduated from BITS-Pilani and obtained a Ph.D. in experimental nuclear physics from the State University of New York at Stony Brook. After postdoctoral work at the Cyclotron Institute, Texas A & M University, he joined the Notre Dame faculty and has been there since. He has held guest professorships at the Free University, Amsterdam, the Netherlands; BARC, Mumbai; GSI, Germany; TIFR, Mumbai; RIKEN, Japan; Peking University, Beijing; Xi'an Jiaotong Univ, Xi'an; and BITS-Pilani. He is a Fellow of the American Physical Society and the American Association for the Advancement of Science.  He also was a Fulbright Senior Scholar and a JSPS Fellow during 2022-23 and is a Fulbright Specialist on Physics Education through 2026. The current focus of his research work is low-energy nuclear structure, with special emphasis on connection of nuclear physics to the physics of neutron stars.
