Finite Groups for the Kummer Surface: The Genetic Code and a Quantum Gravity Analogy
Quantum Reports, 2021 The Kummer surface was constructed in 1864. It corresponds to the desingularization of the quotient of a 4-torus by 16 complex double points. Kummer surface is known to play a role in some models of quantum gravity.

Periodic Modification of the Boerdijk–Coxeter Helix (tetrahelix)
Mathematics, 2019 The Boerdijk−Coxeter helix is a helical structure of tetrahedra which possesses no non-trivial translational or rotational symmetries. In this document, we develop a procedure by which this structure is modified to obtain both translational and ...

Dixon-Rosenfeld lines and the Standard Model
European Physical Journal C: Particles and Fields, 2023 We present three new coset manifolds named Dixon-Rosenfeld lines that are similar to Rosenfeld projective lines except over the Dixon algebra $$\mathbb {C}\otimes \mathbb {H}\otimes \mathbb {O}$$ C ⊗ H ⊗ O .

Graph Coverings for Investigating Non Local Structures in Proteins, Music and Poems
Sci, 2021 We explore the structural similarities in three different languages, first in the protein language whose primary letters are the amino acids, second in the musical language whose primary letters are the notes, and third in the poetry language whose ...

Perspectives on electric dipole moments of atoms and molecules [PDF]
EPJ Web of Conferences, 2023 Searches for a permanent electric dipole moment (EDM) of a fundamental particle started with the key idea by Ramsey and Purcell of exploitation of discrete symmetries, such as parity, more than seven decades ago.

(2+1) gravity for higher genus in the polygon model [PDF]
, 2004 We construct explicitly a (12g − 12)-dimensional space P of unconstrained and independent initial data for ’t Hooft’s polygon model of (2+1) gravity for vacuum spacetimes with compact genus-g spacelike slices, for any g ≥ 2.

On quantum gravity and quantum gravity phenomenology
The Sixteenth Marcel Grossmann Meeting, 2023 This article summarizes a new approach to quantum gravity based on the concepts of modular spacetime, Born geometry, and metastring theory and their applications to quantum gravity phenomenology. In particular, we discuss a new understanding of dark matter in terms of metaparticles (zero modes of the metastring) and its relation to dark energy (the ...
