Ricci polynomial gravity
Xin Hao, Liu Zhao
We study a novel class of higher curvature gravity models in spacetime dimensions which we call Ricci polynomial gravity. The action is consisted purely of a polynomial in Ricc…
Fluids and vortex from constrained fluctuations around C-metric black hole
Xin Hao, Bin Wu, Liu Zhao
By foliating the four-dimensional C-metric black hole spacetime, we consider a kind of initial-value-like formulation of the vacuum Einstein's equation, the holographic initial dat…
Near horizon symmetry and entropy of black holes in gravity and conformal gravity
Jun Li, Kun Meng, Liu Zhao
We generalize the Noether current method proposed by Majhi and Padmanabhan recently to gravity and conformal gravity and analyze the near horizon symmetry of black holes in…
Compressible forced viscous fluid from product Einstein manifolds
Xin Hao, Bin Wu, Liu Zhao
We consider the fluctuation modes around a hypersurface in a -dimensional product Einstein manifold, with taken either near the horizon or at some finite cutoff…
Flat space compressible fluid as holographic dual of black hole with curved horizon
Xin Hao, Bin Wu, Liu Zhao
We consider the fluid dual of -dimensional vacuum Einstein equation either with or without a cosmological constant. The background solutions admit black hole event horizons…
