Entanglement, Soft Modes, and Celestial Holography
Hong Zhe Chen, Robert C. Myers, Ana-Maria Raclariu
We evaluate the vacuum entanglement entropy across a cut of future null infinity for free Maxwell theory in four-dimensional Minkowski spacetime. The Weyl invariance of 4D Maxwell…

Disentanglement as a strong cosmic censor
Hong Zhe Chen
If entanglement builds spacetime, then conversely, disentanglement ought to destroy spacetime. From the quantum null energy condition and quantum focusing conjecture, we obtain dis…

Entanglement, Soft Modes, and Celestial CFT
Hong Zhe Chen, Robert Myers, Ana-Maria Raclariu
We revisit the calculation of vacuum entanglement entropy in free Maxwell theory in four-dimensional Minkowski spacetime. Weyl invariance allows for this theory to be embedded as a…
