On the horizon entropy of a causal set
Ludovico Machet, Jinzhao Wang
We discuss how to define a kinematical horizon entropy on a causal set. We extend a recent definition of horizon molecules to a setting with a null hypersurface crossing the horizo…
Revisiting the equality conditions of the data processing inequality for the sandwiched Rényi divergence
Jinzhao Wang, Henrik Wilming
We provide a transparent, simple and unified treatment of recent results on the equality conditions for the data processing inequality (DPI) of the sandwiched quantum Rényi diverge…
On the continuum limit of Benincasa-Dowker-Glaser causal set action
Ludovico Machet, Jinzhao Wang
We study the continuum limit of the Benincasa-Dowker-Glaser causal set action on a causally convex compact region. In particular, we compute the action of a causal set randomly spr…
Outer entropy = Bartnik-Bray inner mass, and the gravitational ant conjecture
Jinzhao Wang
Entropy and energy are found to be closely tied on our quest for quantum gravity. We point out an interesting connection between the recently proposed outer entropy, a coarse-grain…
The small sphere limit of quasilocal energy in higher dimensions along lightcone cuts
Jinzhao Wang
The problem of quasilocal energy has been extensively studied mainly in four dimensions. Here we report results regarding the quasilocal energy in spacetime dimension . Af…
