A Holographic P-wave Superconductor ModelSep 19 2013Dec 09 2013We study a holographic p-wave superconductor model in a four dimensional Einstein-Maxwell-complex vector field theory with a negative cosmological constant. The complex vector field is charged under the Maxwell field. We solve the full coupled equations ... More
A Holographic Study on Vector Condensate Induced by a Magnetic FieldSep 09 2013Dec 02 2013We study a holographic model with vector condensate by coupling the anti-de Sitter gravity to an Abelian gauge field and a charged vector field in $(3+1)$ dimensional spacetime. In this model there exists a non-minimal coupling of the vector filed to ... More
Entanglement Entropy and Wilson Loop in Stückelberg Holographic Insulator/Superconductor ModelSep 05 2012Oct 18 2012We study the behaviors of entanglement entropy and vacuum expectation value of Wilson loop in the St\"{u}ckelberg holographic insulator/superconductor model. This model has rich phase structures depending on model parameters. Both the entanglement entropy ... More
Face-Centered-Cubic B$_{80}$ Metal: Density functional theory calculationsNov 08 2008By means of ab initio calculations within the density functional theory, we have found that B80 fullerenes can condense to form stable face-centered-cubic fcc solids. It is shown that when forming a crystal, B80 cages are geometrically distorted, the ... More
Strain-induced large band-gap topological insulator in a new stable silicon allotrope: dumbbell siliceneOct 28 2015By the generalized gradient approximation in framewok of density functional theory, we investigate a 2D topological insulator of new silicon allotrope (call dumbbell silicene synthesized recently by Cahangirov et al) through tuning external compression ...

Critical Behavior of Ferromagnetic Ising Model on Triangular LatticeAug 31 2008Oct 11 2008We apply a new updating algorithm scheme to investigate the critical behavior of the two-dimensional ferromagnetic Ising model on a triangular lattice with nearest neighbour interactions. The transition is examined by generating accurate data for large ... More
Determining the evolutionary stage of the delta Scuti star HIP 80088 with asteroseismologySep 06 2018We have computed a grid of theoretical models to fit the twelve oscillation modes of HIP 80088 observed by K2. HIP 80088 is determined to be a pre-main sequence star, in which CN cycle has not arrived at the equilibrium state. Mass fractions of C12 and ... More
Let's Play Mahjong!Mar 08 2019Mahjong is a very popular tile-based game commonly played by four players. Each player begins with a hand of 13 tiles and, in turn, players draw and discard (i.e., change) tiles until they complete a legal hand using a 14th tile. In this paper, we initiate ... More
Nonlinear elliptic equations with a singular perturbation on compact Lie groups and Homogeneous spacesMay 17 2012Feb 03 2013This paper is devoted to the study of a class of singular perturbation elliptic type problems on compact Lie groups or homogeneous spaces $\mathcal{M}$. By constructing a suitable Nash-Moser-type iteration scheme on compact Lie groups and homogeneous ... More
