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…

Quantum Anomalies of Tensionless Bosonic Strings
Bin Chen, Zezhou Hu
We systematically investigate and compare the worldsheet actions, BRST structures and the quantum anomalies of four different formulations of tensionless () bosonic string t…

Symmetries and Critical Dimensions of Tensionless Branes
Bin Chen, Zezhou Hu
In this work, we investigate the worldsheet symmetry of bosonic brane theories and its quantum consistency in the tensionless limit. We find that the residual worldsheet symmetry a…
