Ragib Farhat Hasan (from Dhaka, Bangladesh) is currently enrolled in the Master of Philosophy (Physics & Astronomy) degree, in which he is investigating the finite density dependence of the foundation of matter using Lattice QCD techniques. His research (supported by the University of Adelaide Research Scholarship) aims to provide the world’s first insight into how the ground state field structure changes in the presence of matter.
Previously, Ragib completed the Bachelor of Science (Space Science & Astrophysics) degree from University of Adelaide, where he achieved the Global Academic Excellence Award in support of his studies. In recognition of his brilliant academic results and overall contribution to the school community, Ragib received the Gold Medal of Academic Excellence during his high school graduation.
Ragib is also a multi-time national and regional Mathematical Olympiad medalist, and these accolades provided him the opportunity to be a participant in the Bangladesh Mathematical Olympiad Camp, which ignited his passion for pure sciences and ultimately lead him to theoretical Physics: the field of exploratory research where Ragib aspires to push the boundaries of human understanding of nature, and in the process, continue to push himself to the limits of his abilities and beyond to explore his own potential to the ultimate.
There are eight chromo-electric and eight chromo-magnetic fields composing the Quantum-Chromodynamics (QCD) vacuum. The crucial, non-perturbative features of the QCD vacuum are the dynamical generation of mass through chiral symmetry breaking and the confinement of quarks. A finite density of quarks within neutron stars alters the foundation of matter, which suggests an important role for quark deconfinement at high matter densities. However, the reasons for this phenomenon are yet to be confirmed, although numerous speculations exist.
My research aims to analyse the changes in the quantum chromo-electromagnetic field configurations of the ground state fields of pure SU(2) colour gauge fields at finite density and examine how these field structures change with increasing matter density. As a result, it will quantify and explain the finite density dependence of the foundation of matter.
The numerical and analytical techniques developed during my research will be beneficial in the study of other finite density systems (e.g. supernovae, moments after the Big Bang etc.). The results will provide the world’s first insight into how the ground state field structure changes in the presence of matter. The conclusions will also advance the understanding of QCD interactions that underpin the natural phenomena of the universe.
