Optimal electron propagation on a quantum chain by a topological phase
S. Paganelli, G. L. Giorgi, F. de Pasquale
We study the quantum diffusion of an electron in a quantum chain starting from an initial state localized around a given site. As the wavepacket diffuses, the probability of recons…

Ground-state factorization and quantum phase transition in dimerized spin chains
Gian Luca Giorgi
We study the occurrence of ground-state factorization in dimerized spin chains in a transverse field. Together with the usual ferromagnetic and antiferromagnetic regimes, a th…
