Entanglement renormalization and boundary critical phenomena
P. Silvi, V. Giovannetti, P. Calabrese +2
The multiscale entanglement renormalization ansatz is applied to the study of boundary critical phenomena. We compute averages of local operators as a function of the distance from…
Velocity-modulation control of electron-wave propagation in graphene
Arnaud Raoux, Marco Polini, Reza Asgari +3
Wave propagation control by spatial modulation of velocity has a long history in optics and acoustics. We address velocity-modulation control of electron wave propagation in graphe…
Critical properties of homogeneous binary trees
P. Silvi, V. Giovannetti, S. Montangero +3
Many-body states whose wave-function admits a representation in terms of a uniform binary-tree tensor decomposition are shown to obey to power-law two-body correlations functions.…
Entanglement and magnetic order
Luigi Amico, Rosario Fazio
In recent years quantum statistical mechanics have benefited of cultural interchanges with quantum information science. There is a bulk of evidence that quantifying the entanglemen…
SQUID Detection of Quantized Mechanical Motion
Stefano Pugnetti, Yaroslav M. Blanter, Rosario Fazio
We predict that quantized mechanical motion can be detected by embedding a mechanical resonator into a quantum SQUID. If the system is tuned to the regime when a plasma frequency o…
Blockade and Counterflow Supercurrent in exciton-condensate Josephson junctions
Fabrizio Dolcini, Diego Rainis, Fabio Taddei +3
We demonstrate that perfect conversion between charged supercurrents in superconductors and neutral supercurrents in electron-hole pair condensates is possible via a new Andreev-li…
