Analytical approach of late-time evolution in a torsion cosmology
Xi-chen Ao, Xin-zhou Li, Ping Xi
In this letter, we study the late-time evolution of a torsion cosmology only with the spin- mode. We find three kinds of analytical solutions with a constant affine scalar cur…
Semi-Holographic Universe
Hongsheng Zhang, Xin-Zhou Li, Hyerim Noh
By assuming that a dark component (dark energy) in the universe strictly obeys the holographic principle, that is, its entropy is one fourth of the apparent horizon, we find that t…
The Casimir force of Quantum Spring in the (D+1)-dimensional spacetime
Xiang-hua Zhai, Xin-zhou Li, Chao-Jun Feng
The Casimir effect for a massless scalar field on the helix boundary condition which is named as quantum spring is studied in our recent paper\cite{Feng}. In this paper, the Casimi…
New mechanism to cross the phantom divide
Yunshuang Du, Hongsheng Zhang, Xin-Zhou Li
Recently, type Ia supernovae data appear to support a dark energy whose equation of state crosses -1, which is a much more amazing problem than the acceleration of the universe…
Non-Gaussianity with Lagrange Multiplier Field in the Curvaton Scenario
Chao-Jun Feng, Xin-Zhou Li
In this paper, we will use -formalism to calculate the primordial curvature perturbation for the curvaton model with a Lagrange multiplier field. We calculate the non…
Quantum Spring from the Casimir Effect
Chao-Jun Feng, Xin-Zhou Li
The Casimir effect arises not only in the presence of material boundaries but also in space with nontrivial topology. In this paper, we choose a topology of the flat -dimens…
