Boundaries of Quantum Field Theories

Diptimoy Ghosh


Effective Field Theories (or Quantum Field Theories at long distances or low energies) find applications in diverse branches of physics, in particular, particle physics, cosmology, and condensed matter systems. Thus narrowing down the space of `consistent' Effective Field Theories (EFTs) is an important and useful exercise. In this talk, I will discuss how low-energy EFTs can be constrained using sacred physical principles like relativistic causality and unitarity.
