Constraining bulk-to-boundary correlators under Poincaré symmetry
Jiang Long, Jing-Long Yang
It is well known that a general two-point function cannot be uniquely determined by Poincaré symmetry. In this paper, we show that bulk-to-boundary correlators are highly constrai…
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 shape optimization for fourth order Steklov eigenvalue problems
Changwei Xiong, Jinglong Yang, Jinchao Yu
We study three types of fourth-order Steklov eigenvalue problems. For the first two of them, we derive the asymptotic expansion of their spectra on Euclidean annular domains $\math…
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…
