Numerical prescriptions of early-time divergences of the in-in formalism
Duc Huy Tran, Yi Wang, Juanyi Yang +1
In quantum field theory, the in and out states can be related to the full Hamiltonian by the prescription. A Wick rotation can further bring the correlation functions to Eucli…

A no-go theorem for generalized vector Galileons on flat spacetime
Cedric Deffayet, A. Emir Gumrukcuoglu, Shinji Mukohyama +1
We explore the possibility for generalized electromagnetism on flat spacetime. For a single copy of gauge theory, we show that the Galileon-type generalization of electromag…

Odd-dimensional de Sitter Space is Transparent
Philip Lagogiannis, Alexander Maloney, Yi Wang
We consider quantum field theory in de Sitter space, focusing on the cases of scalars, spin 1/2 fields, and symmetric and anti-symmetric tensor fields of arbitrary spin. The free f…
