Entanglement features in scattering mediated by heavy particles
Chon Man Sou, Yi Wang, Xingkai Zhang
The amount of information propagated by an intermediate heavy particle exhibits characteristic features in inelastic scatterings with final particles. As the total energy…
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…
On the Decoherence of Primordial Gravitons
Sirui Ning, Chon Man Sou, Yi Wang
It is well-known that the primordial scalar curvature and tensor perturbations, and , are conserved on super-horizon scales in minimal inflation models. However, their…
Chemical-Potential-Assisted Particle Production in FRW Spacetimes
Chon Man Sou, Xi Tong, Yi Wang
We analyze gravitational particle production assisted by chemical potential. By utilizing the uniformly smoothed Stokes-line method and Borel summation, we gain insight into the fi…
