Hydrodynamic transport functions from quantum kinetic theory
E. Calzetta, B. L. Hu, S. Ramsey
Starting from the quantum kinetic field theory [E. Calzetta and B. L. Hu, Phys. Rev. D37, 2878 (1988)] constructed from the closed-time-path (CTP), two-particle-irreducible (2PI) e…

One-loop theory in Robertson-Walker spacetimes: adiabatic regularization and analytic approximation
Carmen Molina-Paris, Paul R. Anderson, Stephen A. Ramsey
The renormalization of a scalar field theory with a quartic self-coupling (a theory) via adiabatic regularization in a general Robertson-Walker spacetime is discussed. The a…
