Knotted optical fields: Seifert fibrations, braided open books and topological constraints
Annalisa Marzuoli, Nicola Sanna
This paper presents a novel framework for studying knotted and braided configurations of optical fields, moving beyond the conventional Hopfion solution based on the Hopf fibration…
Projective Ponzano-Regge spin networks and their symmetries
Vincenzo Aquilanti, Annalisa Marzuoli
We present a novel hierarchical construction of projective spin networks of the Ponzano-Regge type from an assembling of five quadrangles up to the combinatorial 4-simplex compatib…
Conformal variations and quantum fluctuations in discrete gravity
Annalisa Marzuoli, Dario Merzi
After an overview of variational principles for discrete gravity, and on the basis of the approach to conformal transformations in a simplicial PL setting proposed by Luo and Glick…
Symmetric angular momentum coupling, the quantum volume operator and the 7-spin network: a computational perspective
Dimitri Marinelli, Annalisa Marzuoli, Vincenzo Aquilanti +3
A unified vision of the symmetric coupling of angular momenta and of the quantum mechanical volume operator is illustrated. The focus is on the quantum mechanical angular momentum…
Topological effective field theories for Dirac fermions from index theorem
Giandomenico Palumbo, Roberto Catenacci, Annalisa Marzuoli
Dirac fermions have a central role in high energy physics but it is well known that they emerge also as quasiparticles in several condensed matter systems supporting topological or…
Hamiltonian dynamics of a quantum of space: hidden symmetries and spectrum of the volume operator, and discrete orthogonal polynomials
Vincenzo Aquilanti, Dimitri Marinelli, Annalisa Marzuoli
The action of the quantum mechanical volume operator, introduced in connection with a symmetric representation of the three-body problem and recently recognized to play a fundament…
