Entanglement Entropy of the Early Universe in Generalized Chaplygin Gas Model
Pisin Chen, Yuezhen Niu
We provide an explicit calculation of the evolution of the cosmic entanglement entropy in the early universe before the matter dominant era. This is made possible by invoking the g…
Where is hbar Hiding in Entropic Gravity?
Pisin Chen, Chiao-Hsuan Wang
The entropic gravity scenario recently proposed by Erik Verlinde reproduced the Newton's law of purely classical gravity yet the key assumptions of this approach all have quantum m…
Analysing the Effect on CMB in a Parity and Charge Parity Violating Varying Alpha Theory
Debaprasad Maity, Pisin Chen
In this paper we study in detail the effect of our recently proposed model of parity and charge-parity (PCP) violating varying alpha on the Cosmic Microwave Background (CMB) photon…
Gravitomagnetism and spinor quantum mechanics
Ronald J. Adler, Pisin Chen, Elisa Varani
We give a systematic treatment of a spin 1/2 particle in a combined electromagnetic field and a weak gravitational field that is produced by a slowly moving matter source. This pap…
The Early-Time Evolution of the Cosmological Perturbations in f(R) Gravity
Je-An Gu, Tse-Chun Wang, Yen-Ting Wu +2
We investigate the evolution of the linear cosmological perturbations in f(R) gravity, an alternative to dark energy for explaining the late-time cosmic acceleration. We numericall…
Confronting Tracker Field Quintessence with Data
Pao-Yu Wang, Chien-Wen Chen, Pisin Chen
We confront tracker field quintessence with observational data. The potentials considered in this paper include , , , $\exp(βM_{p…
