Journal ArticleDOI
Relevance of sub-surface chip layers for the lifetime of magnetically trapped atoms
B. Zhang,Carsten Henkel,Elmar Haller,S. Wildermuth,Sebastian Hofferberth,Peter Krüger,Jörg Schmiedmayer +6 more
TL;DR: In this paper, the lifetime of magnetically trapped atoms above a planar, layered atom chip structure was investigated, based on the exact magnetic Green function and multi-layer reflection coefficients, where the center of a side guide trap was laterally shifted with respect to the current carrying wire using additional bias fields.
Journal ArticleDOI
A simple quantum gate with atom chips
M. A. Cirone,Antonio Negretti,Antonio Negretti,Tommaso Calarco,Peter Krüger,Jörg Schmiedmayer +5 more
TL;DR: In this paper, a simple scheme for implementing an atomic phase gate using two degrees of freedom for each atom and discuss its realization with cold rubidium atoms on atom chips is presented.
Journal ArticleDOI
The Shapiro effect in atomchip-based bosonic Josephson junctions
Julian Grond,Thomas Betz,Ulrich Hohenester,Norbert J. Mauser,Jörg Schmiedmayer,Thorsten Schumm,Thorsten Schumm +6 more
TL;DR: In this paper, the emergence of Shapiro resonances in tunnel-coupled Bose-Einstein condensates, realizing a bosonic Josephson junction, is analyzed based on an experimentally relevant implementation using magnetic double-well potentials on an atomchip.
Journal ArticleDOI
Analytical pendulum model for a bosonic Josephson junction
Marine Pigneur,Jörg Schmiedmayer +1 more
TL;DR: In this paper, an analytical description of the tunneling dynamics between two coupled Bose-Einstein condensates in the Josephson regime is presented, which relies on the classical analogy with a rigid pendulum and focuses on two dynamical modes of this system: Josephson oscillations and macroscopic quantum self-trapping.
Journal ArticleDOI
Shortcut loading atoms into an optical lattice
TL;DR: In this paper, an effective and fast (few microseconds) procedure for transferring ultra-cold atoms from the ground state in a harmonic trap into the desired bands of an optical lattice is presented.
