Inflationary Magnetogenesis with Broken Local U(1) Symmetry
Guillem Domènech, Chunshan Lin, Misao Sasaki
We point out that a successful inflationary magnetogenesis could be realised if we break the local U(1) gauge symmetry during inflation. The effective electric charge is fixed as a…
Quantum Cauchy Surfaces in Canonical Quantum Gravity
Chun-Yen Lin
For a Dirac theory of quantum gravity obtained from the refined algebraic quantization procedure, we propose a quantum notion of Cauchy surfaces. In such a theory, there is a kerne…
Resonant Primordial Gravitational Waves Amplification
Chunshan Lin, Misao Sasaki
We propose a mechanism to evade the Lyth bound in models of inflation. We minimally extend the conventional single-field inflation model in general relativity (GR) to a theory with…
Effective Field Theory of Broken Spatial Diffeomorphisms
Chunshan Lin, Lance Z. Labun
We study the low energy effective theory describing gravity with broken spatial diffeomorphism invariance. In the unitary gauge, the Goldstone bosons associated with broken diffeom…
