Quantum Field Theories

Some quantum field theories (QFTs) like quantum chromodynamics (the theory that governs the strong nuclear force) have an intriguing property called asymptotic freedom. When present, this feature of the QFTs allows us to understand the very high energy limit of the physical systems.  

I am incredibly grateful for the generous support from the URS office under the Summer IDEA Grant, which allowed me to work with Dr. Shailesh Chandrasekharan on this intriguing field of research. In particular, we studied how a certain class of QFTs (that has finite degrees of freedom per space-time lattice site) can achieve asymptotic freedom. The exciting result of this research not only shed lights on this class of theories, but can also help us study QFTs on quantum computers in the future.
