Tight-Binding realization of non-abelian gauge fields: singular spectra and wave confinement
Y. Hernández-Espinosa, E. Sadurní
We present a geometric construction of a lattice that emulates the action of a gauge field on a fermion. The construction consists of a square lattice made of polymeric sites, wher…
On the electronic structure of benzene and borazine: An algebraic description
Y. Hernández-Espinosa, R. A. Méndez-Sánchez, E. Sadurní
The spectrum of a hexagonal ring is analysed using concepts of group theory and a tight-binding model with first, second and third neighbours. The two doublets in the spectrum are…
Dynamical symmetry in a minimal dimeric complex
E. Sadurní, Y. Hernández-Espinosa
The emergence of non-configurational symmetry is studied in a minimal example. The system under scrutiny consists of a dimeric hexagonal complex with configurational symmetry…
The stabilizer group of honeycomb lattices and its application to deformed monolayers
Y. Hernández-Espinosa, A. S. Rosado, E. Sadurní
Isospectral transformations of exactly solvable models constitute a fruitful method for obtaining new structures with prescribed properties. In this paper we study the stability gr…
