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…
Alternative Derivations of Hawking Radiation
Chon Man Sou
Since the original derivation of Hawking radiation, there have been lots of alternative approaches to show the same fact that black holes emit particles as hot bodies with a temper…
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…
Decoherence of Cosmological Perturbations from Boundary Terms and the Non-Classicality of Gravity
Chon Man Sou, Duc Huy Tran, Yi Wang
We note that the decoherence of inflationary curvature perturbation is dominated by a boundary term of the gravity action. Although this boundary term cannot affect cosmologica…
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…
Gravitational Production of Superheavy Dark Matter and Associated Cosmological Signatures
Lingfeng Li, Tomohiro Nakama, Chon Man Sou +2
We study the gravitational production of super-Hubble-mass dark matter in the very early universe. We first review the simplest scenario where dark matter is produced mainly during…
Cosmic Decoherence: Massive Fields
Junyu Liu, Chon-Man Sou, Yi Wang
We study the decoherence of massive fields during inflation based on the Zurek's density matrix approach. With the cubic interaction between inflaton and massive fields, the reduce…
