Quantum flux operators in the fermionic theory and their supersymmetric extension
Si-Mao Guo, Wen-Bin Liu, Jiang Long
We construct quantum flux operators with respect to the Poincaré symmetry in the massless Dirac theory at future null infinity. An anomalous helicity flux operator emerges from the…
Carrollian propagator and amplitude in Rindler spacetime
Ang Li, Jiang Long, Jing-Long Yang
We study the three-dimensional Carrollian field theory on the Rindler horizon which is dual to a bulk massless scalar field theory in the four-dimensional Rindler wedge. The Carrol…
On the definition of Carrollian amplitudes in general dimensions
Wen-Bin Liu, Jiang Long, Hong-Yang Xiao +1
Carrollian amplitude is the natural object that defines the correlator of the boundary Carrollian field theory. In this work, we will elaborate on its proper definition in general…
Electromagnetic helicity flux operators in higher dimensions
Wen-Bin Liu, Jiang Long, Xin-Hao Zhou
The helicity flux operator is a fascinating quantity that characterizes the angular distribution of the helicity of radiative photons or gravitons and it has many interesting physi…
Feynman rules and loop structure of Carrollian amplitudes
Wen-Bin Liu, Jiang Long, Xiao-Quan Ye
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…
Holographic dictionary from bulk reduction
Wen-Bin Liu, Jiang Long
We propose a holographic dictionary which comes from reducing the bulk theories in an asymptotically flat spacetime to its null infinity. A general boundary theory is characterized…
