Cosmological Collider Signals at Strong Mixing
Xiangwei Wang, Yi Wang, Yunke Zhao
We study cosmological collider signatures in a two-field inflationary system with constant-turn derivative mixing between the canonically normalized curvature fluctuation and a mas…
On Cosmological Correlators with Boundary Contributions
Yanjiao Ma, Dong-Gang Wang, Xiangwei Wang +2
Cosmological correlators receive contributions from both field interactions in the bulk of quasi-de Sitter (dS) spacetime and boundary terms at the end of inflation. While most of…
Interact or Twist: Cosmological Correlators from Field Redefinitions Revisited
Donggang Wang, Xiangwei Wang, Yi Wang +1
In cosmology, correlation functions on a late-time boundary can arise from both field redefinitions and bulk interactions, which are usually believed to generate distinct results.…
Cosmological Bell Tests with Decoherence Effects
Chon Man Sou, Junqi Wang, Yi Wang
The inflationary universe creates particle pairs, which are entangled in their momenta due to momentum conservation. Operators involving the momenta of the fluctuations can be rewr…
A Topological Drive for Spacetime Travel
Tingqi Cai, Yi Wang
We present a toy metric of spacetime travel from topological change. A bubble-like baby universe is detached and re-attached from our universe. Depending on where the bubble is re-…
