BMS modules from path integrals on the coadjoint orbits
Pujian Mao, Xin-Cheng Mao
In this paper, we provide a systematic construction of quantum modules associated with coadjoint orbits of asymptotic symmetry groups through the path integral quantization at one-…
Holography in flipped AdS/: Another approach to dS holography
Bin Chen, Zezhou Hu, Xin-Cheng Mao +1
Motivated by the subtleties in the conventional dS/CFT correspondence, we explore analytic continuation as a constructive route to de Sitter holography. We show that quantum field…
Character of the highest weight module of BMS algebra realized on codimensional-two boundary
Bin Chen, Song He, Pujian Mao +1
In this paper, we investigate the highest weight representation (HWR) of the three and four-dimensional Bondi-Metzner-Sachs (BMS) algebra realized on the codimension-two boundary o…
Quantum field theory in flat spacetime with multiple time directions
Bin Chen, Zezhou Hu, Xin-Cheng Mao
This letter serves as the generalization of the work 2505.16436, where we investigated the quantum field theory in Klein space which has two time directions. We extend studies to t…
QFT in Klein space
Bin Chen, Zezhou Hu, Xin-Cheng Mao
In this paper, we investigate the quantum field theory in Klein space that has two time directions. To study the canonical quantization, we select the ``length of time" as the…
Irrelevant and marginal deformed BMS field theories
Song He, Xin-Cheng Mao
In this study, we investigate various deformations within the framework of Bondi-van der Burg-Metzner-Sachs invariant field theory (BMSFT). Specifically, we explore the impact of B…
