Finite energy spectral function of an anisotropic 2D system of coupled Hubbard chains
P. Ribeiro, P. D. Sacramento, K. Penc
We study the crossover from the one-dimensional to the two-dimensional Hubbard model in the photoemission spectra of weakly coupled chains. The chains with on-site repulsion are tr…

Entanglement in the symmetric sector of qubits
P. Ribeiro, R. Mosseri
We discuss the entanglement properties of symmetric states of qubits. The Majorana representation maps a generic such state into a system of points on a sphere. Entanglemen…
