Generalized Chaplygin gas model: constraints from Hubble parameter versus Redshift Data
Puxun Wu, Hongwei Yu
We examine observational constraints on the generalized Chaplygin gas (GCG) model for dark energy from the 9 Hubble parameter data points, the 115 SNLS Sne Ia data and the size of…
Constraints on a variable dark energy model with recent observations
Puxun Wu, Hongwei Yu
We place, by the maximum likelihood method, constraints on a variable dark energy model with the equation of state using some recent observational data, in…
Entanglement generation in atoms immersed in a thermal bath of external quantum scalar fields with a boundary
Jialin Zhang, Hongwei Yu
We examine the entanglement creation between two mutually independent two-level atoms immersed in a thermal bath of quantum scalar fields in the presence of a perfectly reflecting…
Spontaneous absorption of an accelerated hydrogen atom near a conducting plane in vacuum
Hongwei Yu, Zhiying Zhu
We study, in the multipolar coupling scheme, a uniformly accelerated multilevel hydrogen atom in interaction with the quantum electromagnetic field near a conducting boundary and s…
Can universe exit from phantom inflation due to gravitational back reaction?
Puxun Wu, Hongwei Yu
The effects of the gravitational back reaction of cosmological perturbations are investigated in a phantom inflation model. The effective energy-momentum tensor of the gravitationa…
Spontaneous excitation of an accelerated hydrogen atom coupled with electromagnetic vacuum fluctuations
Zhiying Zhu, Hongwei Yu, Shizhuan Lu
We consider a multilevel hydrogen atom in interaction with the quantum electromagnetic field and separately calculate the contributions of the vacuum fluctuation and radiation reac…
