Dual little strings from F-theory and flop transitions

Journal of High Energy Physics, 2017
A particular two-parameter class of little string theories can be described by M parallel M5-branes probing a transverse affine A N − 1 singularity. We previously discussed the duality between the theories labelled by (N, M) and (M, N).

$SL(2,\mathbb{C})$ Scheme Processing of Singularities in Quantum Computing and Genetics

Axioms, 2023
Revealing the time structure of physical or biological objects is usually performed thanks to the tools of signal processing such as the fast Fourier transform, Ramanujan sum signal processing, and many other techniques.

Quantum Gravity: Motivations and Alternatives [PDF]

, 2009
The mutual conceptual incompatibility between General Relativity and Quantum Mechanics / Quantum Field Theory is generally seen as the most essential motivation for the development of a theory of Quantum Gravity.

Brane-World Gravity [PDF]

, 2010
The observable universe could be a 1+3-surface (the “brane”) embedded in a 1+3+d-dimensional spacetime (the “bulk”), with Standard Model particles and fields trapped on the brane while gravity is free to access the bulk.

Liouville Gravity from Einstein Gravity [PDF]

, 2009
We show that Liouville gravity arises as the limit of pure Einstein gravity in 2+epsilon dimensions as epsilon goes to zero, provided Newton's constant scales with epsilon. Our procedure - spherical reduction, dualization, limit, dualizing back - passes several consistency tests: geometric properties, interactions with matter and the Bekenstein-Hawking

Contravariant gravity on Poisson manifolds and Einstein gravity [PDF]

Classical and Quantum Gravity, 2017
Abstract A relation between gravity on Poisson manifolds proposed in Asakawa et al (2015 Fortschr. Phys . 63 683–704) and Einstein gravity is investigated.

Quasicrystalline spin foam with matter: definitions and examples

Academia Quantum
In this work, we define quasicrystalline spin networks as a subspace within the standard Hilbert space of loop quantum gravity, effectively constraining the states to coherent states that align with quasicrystal geometry structures.

Quasicrystal Tilings in Three Dimensions and Their Empires

Crystals, 2018
The projection method for constructing quasiperiodic tilings from a higher dimensional lattice provides a useful context for computing a quasicrystal’s vertex configurations, frequencies, and empires (forced tiles).

A new class of group field theories for 1st order discrete quantum gravity [PDF]

, 2008
Group Field Theories, a generalization of matrix models for 2d gravity, represent a 2nd quantization of both loop quantum gravity and simplicial quantum gravity.

Lunin-Maldacena backgrounds from the classical Yang-Baxter equation - Towards the gravity/CYBE correspondence [PDF]

, 2014
We consider γ-deformations of the AdS5×S5 superstring as Yang-Baxter sigma models with classical r-matrices satisfying the classical Yang-Baxter equation (CYBE).
