TL;DR: In this article, simple and versatile traps for neutral atoms can be built using the magnetic potentials created by a current-carrying wire and a homogeneous bias field, which can achieve favorable scaling properties and can achieve parameters required for Bose-Einstein.

TL;DR: Physicists can already make ultracold atoms perform quantum tricks in sophisticated magnetic and optical traps, but a fast route to trapping atoms on a microchip opens up new possibilities.

TL;DR: In this paper, the authors proposed a line of interference experiments which may be able to examine the regime of induced elements of reality, based on the hypothesis that models of such elements should exhibit symmetry breaking within quantum evolution.
Abstract: Following almost a century of debate on possible “independent of measurement" elements of reality, or “induced" elements of reality - originally invoked as an ad-hoc collapse postulate, we propose a novel line of interference experiments which may be able to examine the regime of induced elements of reality. At the basis of the proposed experiment, lies the hypothesis that models of “induced" elements of reality should exhibit symmetry breaking within quantum evolution. The described symmetry experiment is thus aimed at being able to detect and resolve spatial symmetry breaking signatures. The proposed experiment stands at the edge of present day technological abilities and will be, so we believe, realizable in the near future.

TL;DR: In this paper, the authors decrivons les principes de base for the construction of tels guides and microscopiques, nous indiquons comment y confiner des atomes, puis nous donnons des exemples d'experiences a base de puces atomiques.
Abstract: On peut realiser une grande variete de potentiels de guidage ou de piegeage en approchant des atomes froids au voisinage d'objets charges ou parcourus par des courants; ceci permet la miniaturisation et l'integration d'elements d'optique atomique, Les surfaces portant ces elements forment des puces atomiques qui, pour l'optique coherente d'ondes de matiere, peuvent constituer la base de nouveaux dispositifs, similaires aux circuits integres pour l'electronique. Nous decrivons les principes de base pour la construction de tels guides et pieges microscopiques, nous indiquons comment y confiner des atomes, puis nous donnons des exemples d'experiences a base de puces atomiques.
