Reconciling cosmic dipolar tensions with a gigaparsec void
Tingqi Cai, Qianhang Ding, Yi Wang
Recent observations indicate a tension between the CMB and quasar dipoles. This tension challenges the cosmological principle. We propose that if we live in a gigaparsec sca…
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…
Quantum Signatures of Gravity from Superpositions of Primordial Massive Particles
Gowtham Amirthya Neppoleon, Aditya Iyer, Vlatko Vedral +1
We study the superposition of primordial massive particles and compute the associated decoherence time scale in the radiation dominated universe. We observe that for lighter primor…
Lattice Simulation of Multi-Stream Inflation
Tingqi Cai, Jie Jiang, Yi Wang
We present the first lattice simulation to investigate the nature of multi-stream inflation. The simulation confirms the physical picture of multi-stream inflation, and with new fi…
