From the Fibonacci Icosagrid to E8 (Part I): The Fibonacci Icosagrid, an H3 Quasicrystal
This paper introduces a new kind of quasicrystal by Fibonacci-spacing a multigrid of a certain symmetry, like H2, H3, T3, etc. Multigrids of a certain symmetry can be used to generate quasicrystals, but multigrid vertices are not a quasicrystal due to ...

Non-perturbative 3d Lorentzian quantum gravity
We have recently introduced a discrete model of Lorentzian quantum gravity, given as a regularized non-perturbative state sum over simplicial Lorentzian spacetimes, each possessing a uniqueWick rotation to Euclidean signature.

(A)Symmetric complexity and the Quantum Mpemba Effect
The Quantum Mpemba Effect (QME) — the counter-intuitive phenomenon where states further from equilibrium can relax faster than those closer to it — challenges standard expectations of quantum thermalization.

Complexity and operator growth in holographic 6d SCFTs
We study Krylov (spread) complexity in strongly coupled six–dimensional N=(1,0) superconformal field theories with holographic duals in massive type IIA supergravity.

Gravitational Lensing Effects from Models of Loop Quantum Gravity with Rigorous Quantum Parameters
Many previous works have studied gravitational lensing effects from Loop Quantum Gravity. So far, gravitational lensing effects from Loop Quantum Gravity have only been studied by choosing large quantum parameters much larger than the Planck scale ...

String Theory – Nomological Unification and the Epicycles of the Quantum Field Theory Paradigm [PDF]
String Theory is the result of the conjunction of three conceptually independent elements: (i) the metaphysical idea of a nomological unity of the forces, (ii) the model-theoretical paradigm of Quantum Field Theory, and (iii) the conflict resulting from ...

Are we at the dawn of quantum-gravity phenomenology?
A handful of recent papers has been devoted to proposals of experiments capable of testing some candidate quantum-gravity phenomena. These lecture notes emphasize those aspects that are most relevant to the questions that come to mind when one is exposed
