The Heisenberg algebra as near horizon symmetry of the black flower solutions of Chern–Simons-like theories of gravity

Conserved charges of minimal massive gravity coupled to scalar field

Recently, the theory of topologically massive gravity non-minimally coupled to a scalar field has been proposed, which comes from the Lorentz–Chern–Simons theory (JHEP 06, 113, 2015), a torsion-free…

BMS type symmetries at null-infinity and near horizon of non-extremal black holes

In this paper we consider a generally covariant theory of gravity, and extend the generalized off-shell ADT current such that it becomes conserved for field dependent (asymptotically) Killing vector…

Asymptotically spacelike warped anti-de Sitter spacetimes in generalized minimal massive gravity

In this paper we show that warped AdS3 black hole spacetime is a solution of the generalized minimal massive gravity (GMMG) and introduce suitable boundary conditions for asymptotically warped AdS3…

Lee-Wald charge and asymptotic behaviors of the Weyl-invariant topologically massive gravity

We apply the Lee–Wald covariant phase space method to the Weyl-invariant topologically massive gravity and compute the corresponding on-shell conserved charges. By using appropriate decay conditions…

Quasi-local Energy in 3D Gravity with Torsion

We show that for generic stationary spacetime and a series of Killing fields, Wald's approach for quasi-local energy could always be generalized to the first order formalism straightforwardly without…

Horizon Fluffs: Near Horizon Soft Hairs as Microstates of Generic AdS3 Black Holes

In [1] the horizon fluffs proposal is put forward to identify microstates of generic non-extremal three-dimensional Banados-Teitelboim-Zanelli (BTZ) black holes. The proposal is that black hole…

Central charges from thermodynamics method in 3D gravity

In the context of guage/gravity duality, we investigate the central charges of a number of 2-dimensional conformal field theories (CFTs) that might live on the boundary of some 3-dimensional (3D) toy…

Black hole entropy in the Chern–Simons-like theories of gravity and Lorentz-diffeomorphism Noether charge

BMS type symmetries at null-infinity and near horizon of non-extremal black holes

In this paper we consider a generally covariant theory of gravity, and extend the generalized off-shell ADT current such that it becomes conserved for field dependent (asymptotically) Killing vector…

Quasilocal conserved charges and holography

We construct a quasi-local formalism for conserved charges in a theory of gravity in the presence of matter fields which may have slow falloff behaviors at the asymptotic infinity. This construction…

Black-hole entropy and thermodynamics from symmetries

Given a boundary of spacetime preserved by a Diff(S1) sub-algebra, we propose a systematic method to compute the zero mode and the central extension of the associated Virasoro algebra of charges.…

Quasi-local conserved charges in Lorenz–diffeomorphism covariant theory of gravity

In this paper, using the combined Lorenz–diffeomorphism symmetry, we find a general formula for the quasi-local conserved charge of the covariant gravity theories in a first order formalism of…

Entropy from conformal field theory at Killing horizons

On a manifold with a boundary, the constraint algebra of general relativity may acquire a central extension, which can be computed using covariant phase space techniques. When the boundary is a…

Black hole entropy and Lorentz-diffeomorphism Noether charge

We show that, in the first or second order orthonormal frame formalism, black hole entropy is the horizon Noether charge for a combination of diffeomorphism and local Lorentz symmetry involving the…

Noether Current, Horizon Virasoro Algebra and Entropy

We provide a simple and straightforward procedure for defining a Virasoro algebra based on the diffeomorphisms near a null surface in a space-time and obtain the entropy density of the null surface…

Quasilocal conserved charges in a covariant theory of gravity.

The formulation for conserved charges is based on the Lagrangian description, and so completely covariant, and a prescription to define quasilocal Conserved charges in any higher derivative gravity is given.

General definition of “conserved quantities” in general relativity and other theories of gravity

In general relativity, the notion of mass and other conserved quantities at spatial infinity can be defined in a natural way via the Hamiltonian framework: Each conserved quantity is associated with…
