First-principle evolution Hamiltonian operator: derivation from ADM quantum constraints and quantum reference-frame conditions
Chun-Yen Lin
For any Dirac theory of quantum gravity governed by a set of well-defined quantum constraints, we discover a universal formula for the exact form of the evolution Hamiltonian opera…
Cosmic Superstrings Revisited in Light of NANOGrav 15-Year Data
John Ellis, Marek Lewicki, Chunshan Lin +1
We analyze cosmic superstring models in light of NANOGrav 15-year pulsar timing data. A good fit is found for a string tension and a string intercommu…
Conformally Invariant Brans-Dicke Loop Quantum Cosmology: A Quantum Geometric Model of Linking Theory
Chun-Yen Lin, Xiangjing Liu, Yongge Ma +1
The loop quantization of the conformal Brans-Dicke cosmology is explored in the spatially flat and Bianchi-I setting. The scalar and conformal constraints governing the canonical m…
The weak coupling theory of all dimensional loop quantum gravity
Gaoping Long, Chun-Yen Lin
The weak coupling loop quantum theory with Abelian gauge group provides us a new perspective to study the weak coupling properties of LQG. In this paper, the weak coupling theory o…
Graviton to Photon Conversion via Parametric Resonance
Robert Brandenberger, Paola C. M. Delgado, Alexander Ganz +1
We study the parametric resonance excitation of the electromagnetic field by a gravitational wave. We show that there is narrow band resonance. For an electromagnetic field in the…
Inflationary epoch in the presence of holographic dark energy
Paola C. M. Delgado, Alexander Ganz, Chunshan Lin
We analyze the effects of the holographic dark energy model in a single field slow-roll inflation, taking into account both the holographic and the dark radiation components. In pa…
