Coherent states versus Glauber-Sudarshan States: Bootstrapping, Schwinger-Keldysh Contours and Lefschetz Thimbles
Heliudson Bernardo, Tatsuya Daniel, Keshav Dasgupta +3
We investigate how, in a highly constrained system such as a four-dimensional diffeomorphism-invariant theory with vanishing bulk Hamiltonian and non-trivial interactions between t…

Vacuum Amplification of Chiral Gravitational Waves and the Stochastic Gravitational Wave Background
Stephon Alexander, Heliudson Bernardo, Yiya Selina Li +1
We investigate cosmological vacuum amplification of gravitational waves in dynamical Chern-Simons gravity. We develop a comprehensive framework to compute graviton production induc…
