Quantum synapse for cold atoms

Published Mar 20, 2007• 1 citation

Abstract

In this paper, the quantum synaptic effect is studied that arisen in the system of two crossed wires excited by the static (DC) and radio-frequency (RF) currents. The potential barrier between the two orthogonal atom streams is controlled electronically and the atoms can be transferred from one wire to another under certain critical values of the RF and DC currents. The results are interesting in the study of quantum interferometry and quantum registering of cold atoms.

INTER-WIRE TRANSFER OF COLD DRESSED ATOMS

Guennadi A. Kouzaev, KARL J. SAND

In this paper, the quantum "synaptic" effect is studied that arises between two cold atom streams guided by cylindrical crossed wires carrying static (DC) and radio-frequency (RF) currents. The potential barrier between the two orthogonal atom streams is controlled electronically and atoms can be transferred from one wire to another under certain critical values of the wires' RF and DC currents and the biasing field. The results are interesting in the study of quantum interferometry and quantum registering of cold atoms.

Quasi-synaptic Effect to Control the Cold Matter Transfer

Guennadi A. Kouzaev, KARL J. SAND

In this paper an electronically controlled cold atom transfer is considered. Two atom streams are guided by wires carrying the DC and RF currents. The trapping areas can touch each other under certain critical values of these currents. At the touching point the atoms are transferred from one wire to another that reminiscent the synaptic effect in the brain. The discovered effect is applicable in quantum interferometry and controlled atom transfer.

RF CONTROLLABLE IOFFE–PRITCHARD TRAP FOR COLD DRESSED ATOMS

Guennadi A. Kouzaev, KARL J. SAND

An Ioffe–Pritchard trap for cold dressed atoms is studied by analytical and numerical simulations. The effective potential in this trap is formed by the static magnetic and radio-frequency fields, and the minimums are formed around the current bars. The depth of the minimums and the overall topology of the effective potential are controlled electronically. The studied regime of the Ioffe–Pritchard trap is of interest for high-sensitivity cold atom interferometers.

Multi-Cell Traps for Registering of Cold Atom Clouds

Guennadi A. Kouzaev, KARL J. SAND

In this letter, the results on the development and simulation of new three-dimensional nanotraps for cold dressed atoms are considered. The traps are the multi-cell structures built by crossed non-touching carbon nanotubes. The trapping effect is tuned by the DC and RF currents to confine the strong- or low-potential seeking atoms far enough from the areas of strong Casimir-Polder and spin-flip forces. It is supposed that the developed and simulated multi-cell structures are pertinent for catching the Bose-Einstein condensates to demonstrate the Josephson effect, and to enable the study of the entanglement of confined clouds in three-dimensional nano-cells.

Radio-Frequency Field-Induced Quantum Interference Effects in Cold Atoms

Long Quan, Shuyu Zhou, Zhou Shan-Yu +1 more

We propose constructing a quantum interference configuration for cold atoms in a magneto-optical trap by applying a radio frequency field, which coherently couples adjacent Zeeman sublevels, in combination with a repumping laser field. One effect of this interference is that a dip exists in the absorption of the repumping light when the radio frequency is scanned. Our prediction has been indirectly detected through the fluorescence of cold atoms in a preliminary experiment.
