Renormalizing an initial state
Hael Collins, R. Holman, Tereza Vardanyan
The intricate machinery of perturbative quantum field theory has largely been devoted to the 'dynamical' side of the theory: simple states are evolved in complicated ways. This art…
A Cosmological Slavnov-Taylor Identity
Hael Collins, R. Holman, Tereza Vardanyan
We develop a method for treating the consistency relations of inflation that includes the full time-evolution of the state. This approach relies only on the symmetries of the infla…
Do Mixed States save Effective Field Theory from BICEP?
Hael Collins, R. Holman, Tereza Vardanyan
The BICEP2 collaboration has for the first time observed the B-mode polarization associated with inflationary gravitational waves. Their result has some discomfiting implications f…
