Mesoscopic superpositions of Tonks-Girardeau states and the Bose-Fermi mapping

We study a one dimensional gas of repulsively interacting ultracold bosons trapped in a double-well potential as the atom-atom interactions are tuned from zero to infinity. We concentrate on the properties of the excited states which evolve from the so-called NOON states to the NOON Tonks-Girardeau states. The relation between the latter and the Bose-Fermi mapping limit is explored. We state under which conditions NOON Tonks-Girardeau states, which are not predicted by the Bose-Fermi mapping, will appear in the spectrum.Comment: 5 pages, 5 figure

A cost sensitiviy analysis for carrier grade wireless mesh networks with tabu optimization

Proceedings of: CARMEN 2010: 2nd International Workshop on CARrier-grade wireless MEsh Networks in conjunction with IEEE INFOCOM 2010: IEEE Conference on Computer Communications Workshops: 15-19 March 2010, San Diego, CaliforniaWe present an insight on the sensitivity of total cost (CAPEX+OPEX) towards various key input parameters for CARrier Grade Wireless MEsh Networks (CARMEN) deployment These input parameters span across three main categories namely the network design options, environment conditions and cost. Various boundary conditions are imposed to allow network operator to understand the impacts of parameters'changes with the highest level of uncertainty. A simple Tabu optimization method is adopted to optimize the node density against target data rate and range.European Community's Seventh Framework ProgramPublicad
