Phase diagram of spin-1 bosons on one-dimensional lattices
Matteo Rizzi, Davide Rossini, Gabriele De Chiara +2
Spinor Bose condensates loaded in optical lattices have a rich phase diagram characterized by different magnetic order. Here we apply the Density Matrix Renormalization Group to ac…
From perfect to fractal transmission in spin chains
Gabriele De Chiara, Davide Rossini, Simone Montangero +1
Perfect state transfer is possible in modulated spin chains, imperfections however are likely to corrupt the state transfer. We study the robustness of this quantum communication p…
Cloning transformations in spin networks without external control
G. De Chiara, R. Fazio, C. Macchiavello +2
In this paper we present an approach to quantum cloning with unmodulated spin networks. The cloner is realized by a proper design of the network and a choice of the coupling betwee…
