Traces and Time: a de Sitter Black Hole correspondence
Cesar Gomez
We describe how general covariance for QFT defined on a space-time background with horizons leads to the need of adding an extra quantum degree of freedom. The definition of traces…
Clocks, Algebras and Cosmology
Cesar Gomez
Gauge invariant local observables describing primordial scalar quantum fluctuations in Inflationary Cosmology are identified as elements of a type de Sitter crossed product al…
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…
The quantum de Sitter root of quasi de Sitter observables: a pedagogical review
Cesar Gomez, Raul Jimenez
In inflationary cosmology the quasi de Sitter graceful exit allows us to measure the quantum features of the primordial dS phase, in particular, the lack of scale invariance parame…
Quantum Fisher Cosmology: Confronting Observations and the Trans-Planckian Problem
Cesar Gomez, Raul Jimenez
The aim of Quantum Fisher Cosmology is to use the quantum Fisher information about pure de Sitter states to derive model independent observational consequences of the existence of…
Model Independent Prediction of the Spectral Index of Primordial Quantum Fluctuations
Cesar Gomez, Raul Jimenez
One of the most important achievements of inflationary cosmology is to predict a departure from scale invariance of the power spectrum for scalar curvature cosmological fluctuation…
