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…
Carrollian superstring in the flipped vacuum
Bin Chen, Zezhou Hu
In this work, we study the spectrum of the Carrollian superstring in the flipped vacuum (the highest-weight representation) in detail. The target spacetime of the Carrollian string…
