Aspects of aperiodicity and randomness in theoretical physics
Leonardo Ortiz, Marcelo Amaral, Klee Irwin
In this work we explore how the heat kernel, which gives the solution to the diffusion equation and the Brownian motion, would change when we introduce quasiperiodicity in the scen…
(2+1)-dimensional Static Cyclic Symmetric Traversable Wormhole: Quasinormal Modes and Causality
Pedro Cañate, Nora Breton, Leonardo Ortiz
In this paper we study a static cyclic symmetric traversable wormhole in dimensional gravity coupled to nonlinear electrodynamics in anti-de Sitter spacetime. The solution…
Black Holes: Information Loss But No Paradox
Sujoy K. Modak, Leonardo Ortíz, Igor Peña +1
The process of black hole evaporation resulting from the Hawking effect has generated an intense controversy regarding its potential conflict with quantum mechanics' unitary evolut…
Brick Walls and AdS/CFT
Bernard S. Kay, L. Ortiz
We discuss the relationship between the bulk-boundary correspondence in Rehren's algebraic holography (and in other 'fixed-background' approaches to holography) and in mainstream '…
Hawking temperature in the eternal BTZ black hole: an example of Holography in AdS spacetime
L. Ortíz
We review the relation between AdS spacetime in 1+2 dimensions and the BTZ black hole. Later we show that a ground state in AdS spacetime becomes a thermal state in the BTZ black h…
Quantum collapse of dust shells in 2+1 gravity
L. Ortíz, M. P. Ryan
This paper considers the quantum collapse of infinitesimally thin dust shells in 2+1 gravity. In 2+1 gravity a shell is no longer a sphere but a ring of matter. The classical equat…
