Signature change as phase transition in holography
Marcelo Botta Cantcheff
In holographic quantum gravity, Euclidean pieces of the spacetime appear in the large N limit as representing semi-classical states of the theory. In this essay, we argue that the…
Spacetime topology from holographic entanglement
Marcelo Botta Cantcheff
An asymptotically AdS geometry connecting two or more boundaries is given by a entangled state, that can be expanded in the product basis of the Hilbert spaces of each CFT living o…
Entanglement from Dissipation and Holographic Interpretation
M. Botta Cantcheff, Alexandre L. Gadelha, Dáfni F. Z. Marchioro +1
In this work we study a dissipative field theory where the dissipation process is manifestly related to dynamical entanglement and put it in the holographic context. Such endeavour…
TFD Extension of Open String Field Theory
M. Botta Cantcheff, R. J. Scherer Santos
We study the application of the rules of Thermo Field Dynamics (TFD) to the covariant formulation of Open String Field Theory (OSFT). We extend the states space and fields accordin…
Area Operators in Holographic Quantum Gravity
Marcelo Botta Cantcheff
We argue that the holographic formula relating entanglement entropy and the area of a minimal surface is the key to define the area of surfaces in the (emergent) spacetime from the…
String in AdS Black Hole: A Thermo Field Dynamic Approach
M. Botta Cantcheff, Alexandre L. Gadelha, Dafni F. Z. Marchioro +1
Based on Maldacena's description of an eternal AdS-black hole, we reassess the Thermo Field Dynamics (TFD) formalism in the context of the AdS/CFT correspondence. The model studied…
