Inflationary Cosmology as flow of integrable weights
Cesar Gomez
We identify the algebra of gauge invariant observables in de Sitter as the subalgebra of the type factor , associated to de Sitter, defined as the centralizer of an…
Duality and Black Hole Evaporation
Cesar Gomez
We construct a model that describes the quantum black hole evaporation unitarily in a Hilbert space of infinite dimension. This construction generalizes Page's finite dimensional a…
The Algebraic Page Curve
Cesar Gomez
The Page curve describing the process of black hole evaporation is derived in terms of a family, parametrized in terms of the evaporation time, of finite type II_1 factors, associa…
On the algebraic meaning of quantum gravity for closed Universes
Cesar Gomez
Assuming the von Neumann algebra associated with a generic de Sitter observer is properly infinite (type III) we use Connes cocycle to identify the unique ( up to unitary equivalen…
Entanglement, Observers and Cosmology: a view from von Neumann Algebras
C. Gomez
Infinite entanglement fluctuations appear when a quantum field theory on a causally complete domain of space-time is a type factor. In the weak gravity limit this fac…
Black Hole Quantum Mechanics in the Presence of Species
Gia Dvali, Cesar Gomez, Dieter Lust
Recently within the context of a microscopic quantum theory, the Black Hole's Quantum N-Portrait, it was shown that continuous global symmetries are compatible with quantum black h…
Non-Critical Confining Strings and the Renormalization Group
E. Alvarez, C. Gomez
String vacua for non critical strings satisfying the requirements of Zig-Zag invariance are constructed. The Liouville mode is shown to play the rôle of scale in the Renormalizatio…
String Representation of Wilson Loops
E. Alvarez, C. Gomez, T. Ortin
We explore the consequences of imposing Polyakov's zig/zag-invariance in the search for a confining string. We first find that the requirement of zig/zag-invariance seems to be inc…
