Open AccessFeynman rules and loop structure of Carrollian amplitudes
In this paper, we derive the Carrollian amplitude in the framework of bulk reduction. The Carrollian amplitude is shown to relate to the scattering amplitude by a Fourier transform in this method. We propose F...

Open AccessQuantum flux operators for Carrollian diffeomorphism in general dimensions
We construct Carrollian scalar field theories in general dimensions, mainly focusing on the boundaries of Minkowski and Rindler spacetime, whose quantum flux operators form a faithful representation of Carroll...

Open AccessSymmetry group at future null infinity III: Gravitational theory
We reduce the gravitational theory in an asymptotically flat spacetime to future null infinity. We compute the Poincaré flux operators at future null infinity and construct the supertranslation and superrotati...

Open AccessSymmetry group at future null infinity II: Vector theory
In this paper, we reduce the electromagnetic theory to future null infinity and obtain a vector theory at the boundary. We compute the Poincaré flux operators which could be generalized. We quantize the vector...

Open AccessArea law of connected correlation function in higher dimensional conformal field theory
We present a new area law which is associated with the correlator of OPE blocks in higher dimensional conformal field theories (CFTs). The area law shows similar behaviour as black hole entropy or geometric en...

Open AccessCorrelation function with the insertion of zero modes of modular Hamiltonians
Zero modes of modular Hamiltonian of one interval are found in momentum space for two dimensional massless free scalar theory. Finite correlators are extracted from separate region connected correlation functi...

Open AccessCorrelation function of modular Hamiltonians
We investigate varies correlation functions of modular Hamiltonians defined with respect to spatial regions in quantum field theory. These correlation functions are divergent in general. We extract finite corr...

Open AccessInvariance of Unruh and Hawking radiation under matter-induced supertranslations
Matter fields are supertranslated upon crossing a shock wave, which leads to entanglement of the quantum vacuum between the two regions on either side of the shock wave. We probe this entanglement for a scalar...

Open AccessOn the mutual information in conformal field theory
In this work, we study the universal behaviors in the mutual information of two disjoint spheres in a conformal field theory (CFT). By using the operator product expansion of the spherical twist operator in te...

Open AccessVacua of the gravitational field
The Poincaré invariant vacuum is not unique in quantum gravity. The BMS supertranslation symmetry originally defined at null infinity is spontaneously broken and results in inequivalent Poincaré vacua. In this...

Open AccessHolographic Rényi entropy for CFT with W symmetry
In this paper we investigate the holographic Rényi entropy of two disjoint intervals on complex plane with small cross ratio x for conformal field theory with W symmetry in the ground state, which could be dual t...

Conical defects, black holes and higher spin (super-)symmetry
We study the (super-)symmetries of classical solutions in the higher spin (super-)gravity in AdS3. We show that the symmetries of the solutions are encoded in the holonomy around the spatial circle. When the spat...

Phase structure of higher spin black hole
In this paper, we investigate the phase structure of the black holes with one single higher spin hair, focusing specifically on the spin 3 and spin ...

Black holes in truncated higher spin AdS3 gravity
We study the higher spin black holes in a truncated version of higher spin gravity in AdS 3. This theory contains only finite number of even spins s = 2, 4, · · · , 2N . We mainly focus on...

High spin topologically massive gravity
We propose an action to describe high spin topologically massive gravity with a negative cosmological constant. With the frame-like fields and spin connections being combined into two gauge fields, the action ...

On holographic description of the Kerr-Newman-AdS-dS black holes
In this paper, we study the holographic description of the generic four-dimensional non-extremal Kerr-Newman-AdS-dS black holes. We find that if focusing on the near-horizon region, for the massless scalar sca...

Real-time correlators and hidden conformal symmetry in the Kerr/CFT correspondence
In this paper, we study the real-time correlators in Kerr/CFT, in the low frequency limit of generic non-extremal Kerr(-Newman) black holes. From the low frequency scattering off Kerr-Newman black holes, we sh...
