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…
Axion Isocurvature Collider
Shiyun Lu
Cosmological colliders can preserve information from interactions at very high energy scale, and imprint them on cosmological observables. Taking the squeezed limit of cosmological…
Standard Model from A Supergravity Model with a Naturally Small Cosmological Constant
Shing Yan Li, Yu-Cheng Qiu, S. -H. Henry Tye
Guided by the naturalness criterion for an exponentially small cosmological constant, we present a string theory motivated 4-dimensional non-linear supergravity mod…
Gauge Invariance, Polar Coordinates and Inflation
Ali Akil, Xi Tong
We point out the necessity of resolving the apparent gauge dependence in the quantum corrections of cosmological observables for Higgs-like inflation models. We highlight the fact…
Non-Standard Primordial Clocks from Dynamical Mass in Alternative to Inflation Scenarios
Yi Wang, Zun Wang, Yuhang Zhu
In the primordial universe, oscillations of heavy fields can be considered as standard clocks to measure the expansion or contraction history of the universe. Those standard clocks…
Holographic non-Gaussianities in general single-field inflation
Hiroshi Isono, Toshifumi Noumi, Gary Shiu +2
We use holographic techniques to compute inflationary non-Gaussianities for general single-field inflation, including models with a non-trivial sound speed. In this holographic app…
