Soft Hair on Schwarzschild: A Wrinkle in Birkhoff's Theorem
Chethan Krishnan, Jude Pereira
The double null form of the Schwarzschild metric is usually arrived at by demanding Eddington-Finkelstein (EF) conditions at the horizon. This leads to certain logarithmic fall-off…
Charges for Hypertranslations and Hyperrotations
Chethan Krishnan, Jude Pereira
Hypertranslations and hyperrotations are asymptotic symmetries of flat space, on top of the familiar supertranslations and superrotations. They were discovered in arXiv:2205.01422…
Stability analysis of non-Abelian electric fields
Jude Pereira, Tanmay Vachaspati
We study the stability of fluctuations around a homogeneous non-Abelian electric field background that is of a form that is protected from Schwinger pair production. Our analysis i…
Hypertranslations and Hyperrotations
Chethan Krishnan, Jude Pereira
We study the asymptotic symmetries of Einstein gravity in flat space. Instead of Bondi gauge, we work with the recently introduced special double null gauge, in which $\mathscr{I}^…
A New Gauge for Asymptotically Flat Spacetime
Chethan Krishnan, Jude Pereira
We present a new gauge for asymptotically flat spacetime that can treat future and past null infinities ( or ) democratically. Our gauge is comple…
Page Curve and the Information Paradox in Flat Space
Chethan Krishnan, Vaishnavi Patil, Jude Pereira
Asymptotic Causal Diamonds (ACDs) are a natural flat space analogue of AdS causal wedges, and it has been argued previously that they may be useful for understanding bulk locality…
