Black Hole Evaporation, Quantum Hair and Supertranslations
Cesar Gomez, Sebastian Zell
In a black hole, hair and quantum information retrieval are interrelated phenomena. The existence of any new form of hair necessarily implies the existence of features in the quant…
Phenomenology of the minimal inflation scenario: inflationary trajectories and particle production
Luis Alvarez-Gaume, Cesar Gomez, Raul Jimenez
We discuss the phenomenology of the minimal inflation scenario. We concentrate on two aspects: inflationary trajectories and particle production. Our findings can be summarized in…
Cosmology as a Crossed Product
Cesar Gomez
We suggest a new conceptual frame where inflationary Cosmology is quantum mechanically described using the Hilbert space representation of the crossed product of the type fac…
A Proof of the Axion?
Gia Dvali, Cesar Gomez, Sebastian Zell
We show that the de Sitter quantum breaking bound when applied to QCD exposes the necessity of the axion solution to the strong CP problem. The Peccei-Quinn mechanism emerges as a…
Gravitational Black Hole Hair from Event Horizon Supertranslations
Artem Averin, Gia Dvali, Cesar Gomez +1
We discuss BMS supertranslations both at null-infinity and on the horizon for the case of the Schwarzschild black hole. We show that both kinds of supertranslations lead to infinet…
Critical gravitational collapse: towards a holographic understanding of the Regge region
Luis Alvarez-Gaume, Cesar Gomez, Agustin Sabio Vera +2
We study the possible holographic connection between the Regge limit in QCD and critical gravitational collapse of a perfect fluid in higher dimensions. We begin by analyzing the p…
