Creation of discrete solitons and observation of the Peierls-Nabarro barrier in Bose-Einstein Condensates
V. Ahufinger, A. Sanpera, P. Pedri +2
We analyze the generation and mobility of discrete solitons in Bose-Einstein condensates confined in an optical lattice under realistic experimental conditions. We discuss first th…

Witnessing multipartite entanglement
Mohamed Bourennane, Manfred Eibl, Christian Kurtsiefer +7
We present the experimental detection of genuine multipartite entanglement using entanglement witness operators. To this aim we introduce a canonical way of constructing and decomp…
