Superconductivity in TlBi with a large Kadowaki-Woods ratio
Zhihua Yang, Zhen Yang, Qiping Su +7
In this article, the superconducting and normal state properties of TlBi with the AlB-type structure were studied by the resistivity, magnetization and specific heat measur…
Superconductivity in a new layered nickel-selenide CsNi2Se2
Huimin Chen, Jinhu Yang, Chao Cao +7
The physical properties of CsNiSe were characterized by electrical resistivity, magnetization and specific heat measurements. We found that the stoichiometric CsNi$_{2}…
Multiband Superconductivity of Heavy Electrons in TlNi2Se2 single crystal
Hangdong Wang, Chiheng Dong, Qianhui Mao +7
Superconductivity has been first observed in TlNiSe at T=3.7 K and appears to involve heavy electrons with an effective mass =1420 , as inferred from th…
Constraints of the equation of state of dark energy from current and future observational data by piecewise parametrizations
Qiping Su, Xi He, Rong-Gen Cai
The model-independent piecewise parametrizations (0-spline, linear-spline and cubic-spline) are used to estimate constraints of equation of state of dark energy () from cur…
Constraints of Dark Energy at High Redshift
Qiping Su, Rong-Gen Cai
Constrains of dark energy (DE) at high redshift from current and mock future observational data are obtained. It is found that present data give poor constraints of DE even beyond…
Figure of Merit and Different Combinations of Observational Data Sets
Qiping Su, Zhong-Liang Tuo, Rong-Gen Cai
To constrain cosmological parameters, one often makes a joint analysis with different combinations of observational data sets. In this paper we take the figure of merit (FoM) for D…
Bondi-Sachs metrics and Photon Rockets
Huabin Ge, Mingxing Luo, Qiping Su +2
We study the Bondi-Sachs rockets with nonzero cosmological constant. We observe that the acceleration of the systems arises naturally in the asymptotic symmetries of (anti-) de Sit…
Notes on Ghost Dark Energy
Rong-Gen Cai, Qiping Su, Zhong-Liang Tuo +1
We study a phenomenological dark energy model which is rooted in the Veneziano ghost of QCD. In this dark energy model, the energy density of dark energy is proportional to Hubble…
Probing the dynamical behavior of dark energy
Rong-Gen Cai, Qiping Su, Hong-Bo Zhang
We investigate dynamical behavior of the equation of state of dark energy by employing the linear-spline method in the region of low redshifts from observational data (SnI…
On the Dark Sector Interactions
Rong-Gen Cai, Qiping Su
It is possible that there exist some interactions between dark energy (DE) and dark matter (DM), and a suitable interaction can alleviate the coincidence problem. Several phenomeno…
Approximate Relations in Quintessence Models
Mingxing Luo, Qiping Su
Quintessence field is a widely-studied candidate of dark energy. There is "tracker solution" in quintessence models, in which evolution of the field at present times is not sen…
Fitting Non-Minimally Coupled Scalar Models to Gold SnIa Dataset
Mingxing Luo, Qiping Su
Non-minimally coupled theories of special potentials are analyzed numerically. Such theories yield equations of state and oscillations of the cosmological expansion, which a…
