An analogy is explored between a setup of three atomic traps coupled via tunneling and an internal atomic three-level system interacting with two laser fields. Within this scenario we describe a STIRAP like process which allows to move an atom between the ground states of two trapping potentials and analyze its robustness. This analogy is extended to other(More)
We study entanglement generation via particle transport across a one-dimensional system described by the Bose-Hubbard Hamiltonian. We analyze how the competition between interactions and tunneling affects transport properties and the creation of entanglement in the occupation number basis. Alternatively, we propose to use spatially delocalized quantum bits,(More)
Crystallization of a family 9 beta-1,4-glucanase from the thermoacidophilic bacterium Alicyclobacillus acidocaldarius CelA is reported. Thin plates can be obtained by hanging-drop vapour-diffusion crystallization in high concentrations (60%) of MPD. These crystals are unusual in that they do not bind the dye IZIT in the mother liquor and do not appear to(More)
