Nanowire atomchip traps for sub-micron atom-surface distances (2009)
Salem, R., Japha, Y., Chabé, J., Hadad, B., Keil, M., Milton, K. A., ...
We present an analysis of magnetic traps for ultracold atoms based on current-carrying wires with sub-micron dimensions. We analyze the physical limitations of these conducting wires, as well as how...
Trapping cold atoms using surface-grown carbon nanotubes (2008)
Petrov, P. G., Machluf, S., Younis, S., Macaluso, R., David, T., Hadad, B., ...
We present a feasibility study for loading cold atomic clouds into magnetic traps created by single-wall carbon nanotubes grown directly onto dielectric surfaces. We show that atoms may be captured...
Magnetic interactions of cold atoms with anisotropic conductors (2008)
David, T., Japha, Y., Dikovsky, V., Salem, R., Henkel, C., Folman, R.
We analyze atom-surface magnetic interactions on atom chips where the magnetic trapping potentials are produced by current carrying wires made of electrically anisotropic materials. We discuss a...
Organized Current Patterns in Disordered Conductors (2008)
Japha, Y., Entin-Wohlman, O., David, T., Salem, R., Aigner, S., Schmiedmayer, J., ...
We present a general theory of current deviations in straight current carrying wires with random imperfections, which quantitatively explains the recent observations of organized patterns of magnetic...
Long-Range Order in Electronic Transport through Disordered Metal Films (2008)
Aigner, S., Della Pietra, L., Japha, Y., Entin-Wohlman, O., David, T., Salem, R., ...
Ultracold atom magnetic field microscopy enables the probing of current flow patterns in planar structures with unprecedented sensitivity. In polycrystalline metal (gold) films we observe long-range...
Using time reversal symmetry for sensitive incoherent matter-wave Sagnac interferometry (2007)
Japha, Y., Arzouan, O., Avishai, Y., Folman, R.
We present a theory of the transmission of incoherent guided matter-waves through Sagnac interferometers. Interferometer configurations with only one input and one output port have a property similar...
High-Q micro-resonators for trapping and detecting a single atom on a chip (2007)
Rosenblit, M., Japha, Y., Horak, P., Folman, R.
Recent progress in the manufacturing of high Q dielectric microresonant structures enables their use as photonic devices that can manipulate and/or detect single atoms on a nanometer scale. Of...
Reduction of Magnetic Noise in Atom Chips by Material Optimization (2005)
Dikovsky, V., Japha, Y., Henkel, C., Folman, R.
We discuss the contribution of the material type in metal wires to the electromagnetic fluctuations in magnetic microtraps close to the surface of an atom chip. We show that significant reduction of...
Motion of a condensate in a shaken and vibrating harmonic trap (2002)
The dynamics of a Bose-Einstein condensate (BEC) in a time-dependent harmonic trapping potential is determined for arbitrary variations of the position of the center of the trap and its frequencies....
Adiabatic Output Coupling of a Bose Gas at Finite Temperatures (2000)
Choi, S., Japha, Y., Burnett, K.
We develop a general theory of adiabatic output coupling from trapped atomic Bose-Einstein Condensates at finite temperatures. For weak coupling, the output rate from the condensate, and the excited...
The Faraday Quantum Clock and Non-local Photon Pair Correlations (1999)
We study the use of the Faraday effect as a quantum clock for measuring traversal times of evanescent photons through magneto-refractive structures. The Faraday effect acts both as a phase-shifter...
