Surface charges in Chern-Simons gravity with deformation
Miao He, Song He, Yi-hong Gao
The deformed 2D CFTs correspond to AdS gravity with Dirichlet boundary condition at finite cutoff or equivalently a mixed boundary condition at spatial infinity. In…
-deformed WZW models from Chern-Simons AdS gravity with mixed boundary conditions
Miao He, Yi-hong Gao
In this work we consider AdS gravitational theory with certain mixed boundary conditions at spatial infinity. Using the Chern-Simons formalism of AdS gravity, we find that…
The boundary theory of a spinor field theory on the Bruhat-Tits tree
Feng Qu, Yi-hong Gao
For a spinor field theory on the Bruhat-Tits tree, we calculate the action and the partition function of its boundary theory by integrating out the interior of the Bruhat-Tits tree…
On the symmetry of deformed CFT
Miao He, Yi-hong Gao
We propose a symmetry of deformed 2D CFT, which preserves the trace relation. The deformed conformal killing equation is obtained. Once we consider the background metric…
Scalar fields on AdS
Feng Qu, Yi-hong Gao
We obtain a subgroup of the isometry group of AdS (a -adic version of AdS alternative to the Bruhat-Tits tree). We propose a candidate for the scalar bulk action and equation…
Hagedorn transition and topological entanglement entropy
Fen Zuo, Yi-Hong Gao
Induced by the Hagedorn instability, weakly-coupled gauge theories on a compact manifold exhibit a confinement/deconfinement phase transition in the large- limit. Recentl…
Thermodynamics of large- gauge theories on a sphere: weak versus strong coupling
Fen Zuo, Yi-Hong Gao
Recently lattice simulation in pure Yang-Mills theory exposes significant quadratic corrections for both the thermodynamic quantities and the renormalized Polyakov loop in the deco…
On neutral scalar radiation by a massive orbiting star in extremal Kerr-Newman black hole
Nan Bai, Yi-Hong Gao, Xiao-bao Xu
In this short note we extend the work of 1401.3746 about gravity waves by a massive orbiting star in an extremal Kerr black hole to an extremal Kerr- Newman black hole for scalar r…
Note on Mutual Information between Two Intervals of Extremal BTZ
Nan Bai, Yi-Hong Gao, Xiao-bao Xu
In this note we compute mutual information between two intervals in CFTs dual to extremal BTZ (UV CFT) and near horizon limit of extremal BTZ (IR CFT) using the replica technique i…
Holographic insulator/superconductor phase transition in Born-Infeld electrodynamics
Nan Bai, Yi-Hong Gao, Guan-Bu Qi +1
We studied holographic insulator/superconductor phase transition in the framework of Born-Infeld electrodynamics both numerically and analytically. First we numerically study the e…
Holographic phase transition in a non-critical holographic model
Sheng-liang Cui, Yi-hong Gao, Wei-shui Xu
We consider a holographic model constructed from the intersecting brane configuration D4-/D4 in noncritical string theory. We study the chiral phase diagram of this…
Note on a non-critical holographic model with a magnetic field
Sheng-liang Cui, Yi-hong Gao, Yunseok Seo +2
We consider a noncritical holographic model constructed from an intersecting brane configuration D4/-D4 with an external magnetic field. We investigate the influence…
A Note on Chiral Symmetry Breaking from Intersecting Branes
Yi-hong Gao, Jonathan P. Shock, Wei-shui Xu +1
In this paper, we will consider the chiral symmetry breaking in the holographic model constructed from the intersecting brane configuration, and investigate the Nambu-Goldstone bos…
Jet quenching parameters of Sakai-Sugimoto Model
Yi-hong Gao, Wei-shui Xu, Ding-fang Zeng
Using gauge theory/string duality, we calculated the jet quenching parameter of the Sakai-Sugimoto model in various phases. Being different from the SYM t…

Yi-hong Gao, Wei-shui Xu, Ding-fang Zeng
The dissipative dynamics of a heavy quark passing through charged thermal plasmas of strongly coupled super Yang-Mills theory is studied using AdS/CFT. We compute the…
Yang-Type Monopoles In 5 Dimensional Curved Space-Time
Ding-fang Zeng, Wei-shui Xu, Yi-hong Gao
Motivated by Gibbons and Townsend's recent work, we construct Yang-Type monopoles in maximally symmetric space-time. We then analyze the dependence of horizon structure of the spac…
NGN, QCD_2 and chiral phase transition from string theory
Yi-hong Gao, Weishui Xu, Ding-fang Zeng
We construct a D2-D8- configuration in string theory, it can be described at low energy by two dimensional field theory. In the weak coupling region, the low energy theor…
Super-horizon Perturbations and CMBA
Ding-fang Zeng, Yi-hong Gao
We provided a gedanken experiment and argued that since observers inside a given Hubble volume could not detect the super horizon perturbation modes as real perturbations, these mo…
Symmetries, Matrices, and de Sitter Gravity
Yi-hong Gao
Using simple algebraic methods along with an analogy to the BFSS model, we explore the possible (target) spacetime symmetries that may appear in a matrix description of de Sitter g…
Interactions between Dielectric Branes
Yi-hong Gao, Zhong-xia Yang
Quantum corrections to the energy of D0-branes in a constant RR 4-form background are studied. Using the Born-Oppenheimer approximation, we compute the long-range interaction betwe…
Instantons and the monopole-like equations in eight dimensions
Yi-hong Gao, Gang Tian
We search for an abelian description of the Yang-Mills instantons on certain eight dimensional manifolds with the special holonomies and SU(4). By mimicing the Seiberg-Wi…
AdS/CFT Correspondence and Quotient Space Geometry
