Transistorlike behavior of a Bose-Einstein condensate in a triple-well potential
In the last several years considerable efforts have been devoted to developing Bose-Einstein-condensate-based devices for applications such as fundamental research, precision measurements, andExpand
A theoretical analysis of Bose-Einstein condensate based beamsplitters, interferometers, and transistors
Over the last several years considerable efforts have been made to develop BoseEinstein condensate (BEC) based devices for a number of applications including fundamental research, precisionExpand
Increasing the coherence time of Bose-Einstein-condensate interferometers with optical control of dynamics
Atom interferometers using Bose-Einstein condensate that is confined in a waveguide and manipulated by optical pulses have been limited by their short coherence times. We present a theoretical modelExpand
Influence of nonadiabaticity and nonlinearity on the operation of cold-atom beam splitters
The operation of cold-atom beam splitters is analyzed in the context of Bose-Einstein condensate interferometry. We introduce two representative geometries of the splitting region and study influenceExpand
Adjustable Microchip Ring Trap for Cold Atoms and Molecules
We describe the design and function of a circular magnetic waveguide produced from wires on a microchip for atom interferometry using de Broglie waves. The guide is a two-dimensional magnetic minimumExpand
Ex vacuo atom chip Bose-Einstein condensate
Ex vacuo atom chips, used in conjunction with a custom thin walled vacuum chamber, have enabled the rapid replacement of atom chips for magnetically trapped cold atom experiments. Atoms were trappedExpand
Atom chips on direct bonded copper substrates.
TLDR
Two mask options for DBC atom chip fabrication are presented, as well as two methods for etching wire patterns into the copper layer, and the wire aspect ratio that optimizes the magnetic field gradient as a function of power dissipation is determined. Expand
Wave-function recombination instability in cold-atom interferometers
Cold-atom interferometers use guiding potentials that split the wave function of the Bose-Einstein condensate and then recombine it. We present a theoretical analysis of the wave-functionExpand
Collisional Decoherence in Trapped-Atom Interferometers that use Nondegenerate Sources
Abstract : The coherence time, and thus sensitivity, of trapped atom interferometers that use non-degenerate gases are limited by the collisions between the atoms. An analytic model that describesExpand
Theoretical analysis of a single and double reflection atom interferometer in a weakly-confining magnetic trap
The operation of a BEC based atom interferometer, where the atoms are held in a weakly-confining magnetic trap and manipulated with counter-propagating laser beams, is analyzed. A simple analyticExpand
