- 요약The phase diagram of Quantum Chromodynamics (QCD) outlines the various states in which strongly interacting matter can be assumed across varying temperatures and baryon number densities. However, extracting theoretical predictions from QCD is remarkably difficult due to the non-perturbative nature of the strong interaction and numerical methods cannot be applied to high densities due to the fermion sign problem. This work explores non-perturbative methods, such as the large N expansion and novel resummation techniques, to calculate thermodynamic and transport properties valid at all temperatures, densities, and coupling strengths. In particular, we apply our analysis to an O(N) scalar field theory and a unitary Fermi gas, hoping to shed light on the behavior of strongly interacting matter under extreme conditions akin to those found inside neutron stars. We extend our analysis to include PT-symmetric fermions in 3+1 dimensions, offering novel insights into non-Hermitian yet physically relevant systems. Our findings suggest physical observables remain well-defined at momentum scales near and beyond the Landau pole, challenging long-held beliefs that the presence of a Landau pole indicates an incomplete theory.
