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…

Explicit Connections Between Krylov and Nielsen Complexity

Ben Craps, Gabriele Pascuzzi, Juan F. Pedraza +2

We establish a direct correspondence between Krylov and Nielsen complexity by choosing the Krylov basis to be part of the elementary gate set of Nielsen geometry and selecting a Ni…

A Half de Sitter Holography

Taishi Kawamoto, Shan-Ming Ruan, Yu-ki Suzuki +1

A long-standing and intriguing question is: does the holographic principle apply to cosmologies like de Sitter spacetime? In this work, we consider a half dS spacetime wherein a ti…
