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…
Gravitational Waves in Chern-Simons-Gauss-Bonnet Gravity
Tatsuya Daniel, Leah Jenks, Stephon Alexander
It is known that the four-dimensional effective field theory arising from heterotic string theory is general relativity with both a Chern-Simons and Gauss-Bonnet term. We study the…
Beyond general relativity: gravitational waves in non-minimally coupled theories
Stephon Alexander, Tatsuya Daniel, Tucker Manton
Non-minimal couplings between matter and curvature tensors arise in many different contexts. Such couplings modify solutions of general relativity (GR) and therefore can be probed…
Indirect Parametric Resonance of the Electromagnetic Field Driven by an Oscillating SU(2) Dark Matter Condensate
Tatsuya Daniel, Vahid Kamali, Robert Brandenberger
We study a local patch of an axion-like dark sector in Minkowski spacetime, containing an initially homogeneous and isotropic non-Abelian condensate, and a real pseudoscala…
Branching Universes
Anamaria Hell, Tatsuya Daniel
We propose the idea that our Universe is a realization among different possible branches, which can be observationally tested through the modified dispersion relation of the gravit…
Reheating with Axion-SU(2) and Gravitational Chern-Simons Couplings
Tatsuya Daniel, Vahid Kamali
We study the early stages of an oscillatory reheating phase in an inflaton plus spectator axion-SU(2) system, including both an axion-gauge Chern-Simons coupling and…
