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…
A Dynamical Quantum Daemon
J. I. Castro Alatorre, D. Condado, E. Sadurní
We study the irreversibility à la Maxwell from a quantum point of view, involving an arbitrarily large ensemble of independent particles, with a daemonic potential that is capable…
Diffraction of diatomic molecular beams: a model with applications to Talbot-Lau interferometry
D. Condado, J. I. Castro-Alatorre, E. Sadurní
In this article we formulate and solve the problem of molecular beam diffraction when each molecule consists of two interacting bodies. Then, using our results, we present the diff…
Wigner function in the polariton phase space
A. Rosado, E. Sadurní, J. M. Torres
The Wigner function of a dynamical infinite dimensional lattice is studied. A closed differential equation without diffusion terms for this function is obtained and solved. We map…
Diffraction of particles in free fall
D. Condado, J. L. Díaz-Cruz, A. Rosado +1
The problem of a beam of quantum particles falling through a diffractive screen is studied. The solutions for single and double slits are obtained explicitly when the potential is…
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…
