Negative shocks versus static patch holography
Yiming Chen, Douglas Stanford, Haifeng Tang +1
We study a version of de Sitter static patch holography in which the Euclidean gravitational path integral, with an observer worldline included, is conjectured to compute a trace.…

Chaos of Berry curvature for BPS microstates
Yiming Chen, Sean Colin-Ellerin, Ohad Mamroud +1
We expect black hole microstates to differ in their chaotic properties from states associated with other geometries. For supersymmetric black holes, ordinary level statistics canno…

On the phase of the de Sitter density of states
Yiming Chen, Douglas Stanford, Haifeng Tang +1
The one-loop gravitational path integral around Euclidean de Sitter space has a complex phase that casts doubt on a state counting interpretation. Recently, it was proposed t…
