Quantization-scheme-Independent Energy and Its Implications for Holographic Bounds
Ze Li, Hai-Shan Liu, Zi-Qing Xiao +1
In holographic duality, the total energy of the dual field theory is obtained from the holographic renormalization, which depends not only on the bulk geometry but also on the choi…
Thermodynamics of Taub-NUT-AdS Spactimes
Jun-Fei Liu, Hai-Shan Liu
We apply the generalised Komar method proposed in [arxiv:2208.05494] to Taub-NUT-AdS spacetime in the theory of Einstein gravity plus a cosmological constant. Based on a generalise…
Near horizon gravitational charges
Hai-Shan Liu, Pujian Mao
In this paper, we study the near horizon symmetry and gravitational charges in the Newman-Penrose formalism. In particular we investigate the effect from topological terms. We find…
A Note on Kerr/CFT and Wald Entropy Discrepancy in High Derivative Gravities
Hai-Shan Liu, H. Lu
We examine the Kerr/CFT correspondence in Einstein gravity extended with quadratic curvature invariants. We consider two explicit examples in four and five dimensions and compute t…
Large-Charge Limit of AdS Boson Stars with Mixed Boundary Conditions
Shi-Fa Guo, Hai-Shan Liu, H. Lu +1
It was recently shown that charged AdS boson stars can reproduce the universal structure of the lowest scaling dimension in the subsector of a CFT with fixed large global ch…
Revisiting the AdS Boson Stars: the Mass-Charge Relations
Hai-Shan Liu, H. Lu, Yi Pang
Motivated by the recent progress in solving the large charge sector of conformal field theories, we revisit the mass-charge relation of boson stars asymptotic to global AdS. We con…

We study the action growth rate in the Wheeler-DeWitt (WDW) patch for a variety of black holes in Einstein gravity that are asymptotic to the anti-de Sitter spacetime, wit…
AC charge transport in holographic Horndeski gravity
Xi-Jing Wang, Hai-Shan Liu, Wei-Jia Li
In this paper, we investigate the AC charge transport in the holographic Horndeski gravity and identify a metal-semiconductor like transition that is driven by the Horndeski coupli…
Quasi-topological Electromagnetism: Dark Energy, Dyonic Black Holes, Stable Photon Spheres and Hidden Electromagnetic Duality
Hai-Shan Liu, Zhan-Feng Mai, Yue-Zhou Li +1
We introduce the quasi-topological electromagnetism which is defined to be the squared norm of the topological 4-form . A salient property is that its energy-momentum te…
Action Growth of Dyonic Black Holes and Electromagnetic Duality
Hai-Shan Liu, H. Lu
Electromagnetic duality of Maxwell theory is a symmetry of equations but not of the action. The usual application of the `complexity=action' conjecture would thus loose this dualit…
Holographic Complexity Growth Rate in Horndeski Theory
Xing-Hui Feng, Hai-Shan Liu
Based on the context of complexity = action (CA) conjecture, we calculate the holographic complexity of AdS black holes with planar and spherical topologies in Horndeski theory. We…
Violation of Thermal Conductivity Bound in Horndeski Theory

We consider AdS black planar black hole in the four-dimensional Einstein-Maxwell-Horndeski theory with two free axions and analyse the thermodynamics of the black hole. We calculat…
Holographic Heat Current as Noether Current
Hai-Shan Liu, H. Lu, C. N. Pope
We employ the Noether procedure to derive a general formula for the radially conserved heat current in AdS planar black holes with certain transverse and traceless perturbations, f…
Quasi-Topological Ricci Polynomial Gravities
Yue-Zhou Li, Hai-Shan Liu, H. Lu
Quasi-topological terms in gravity can be viewed as those that give no contribution to the equations of motion for a special subclass of metric ansätze. They therefore play no rôle…
Horndeski Gravity and the Violation of Reverse Isoperimetric Inequality
Xing-Hui Feng, Hai-Shan Liu, Wen-Tian Lu +1
We consider Einstein-Horndeski-Maxwell gravity, together with a cosmological constant and multiple Horndeski axions. We construct charged AdS planar black holes in general dimensio…

In this paper, we consider two four-dimensional Horndeski-type gravity theories with scalar fields that give rise to solutions with momentum dissipation in the dual boundary theori…
DC Conductivities from Non-Relativistic Scaling Geometries with Momentum Dissipation
Sera Cremonini, Hai-Shan Liu, Hong Lu +1
We consider a gravitational theory with two Maxwell fields, a dilatonic scalar and spatially dependent axions. Black brane solutions to this theory are Lifshitz-like and violate hy…

Xing-Hui Feng, Hai-Shan Liu, H. Lü +1
We extend an earlier investigation of the thermodynamics of static black holes in an Einstein-Horndeski theory of gravity coupled to a scalar field, by including now an elec- troma…
Black Hole Entropy and Viscosity Bound in Horndeski Gravity
Xing-Hui Feng, Hai-Shan Liu, H. Lü +1
Horndeski gravities are theories of gravity coupled to a scalar field, in which the action contains an additional non-minimal quadratic coupling of the scalar, through its first de…
