Testing cosmic opacity from SNe Ia and Hubble parameter through three cosmological-model-independent methods
Kai Liao, Zhengxiang Li, Jing Ming +1
We use the newly published 28 observational Hubble parameter data () and current largest SNe Ia samples (Union2.1) to test whether the universe is transparent. Three cosmolog…
A unification of RDE model and XCDM model
Kai Liao, Zong-Hong Zhu
In this Letter, we propose a new generalized Ricci dark energy (NGR) model to unify Ricci dark energy (RDE) and XCDM. Our model can distinguish between RDE and XCDM by introducing…
Pruning of CRT-sub-trees
Romain Abraham, Jean-François Delmas, Hui He
We study the pruning process developed by Abraham and Delmas (2012) on the discrete Galton-Watson sub-trees of the Lévy tree which are obtained by considering the minimal sub-tree…
Shape dependent finite-size effect of critical two-dimensional Ising model on a triangular lattice
Xintian Wu, Nickolay Izmailian, Wenan Guo
Using the bond-propagation algorithm, we study the finite-size behavior of the critical two-dimensional Ising model on a finite triangular lattice with free boundaries in five shap…
Low-energy effective theory and two distinct critical phases in a spin-1/2 frustrated three-leg spin tube
Yang Zhao, Shou-Shu Gong, Yong-Jun Wang +1
Motivated by the crystal structures of [(CuCl2tachH)3Cl]Cl2 and Ca3Co2O6, we develop a low-energy effective theory using the bosonization technique for a spin-1/2 frustrated three-…
Loop quantum modified gravity and its cosmological application
Xiangdong Zhang, Yongge Ma
A general nonperturvative loop quantization procedure for metric modified gravity is reviewed. As an example, this procedure is applied to scalar-tensor theories of gravity. The qu…
