Deterministic delivery of a single atom.

چکیده
We report the realization of a deterministic source of single atoms. A standing-wave dipole trap is loaded with one or any desired number of cold cesium atoms from a magneto-optical trap. By controlling the motion of the standing wave, we adiabatically transport the atom with submicrometer precision over macroscopic distances on the order of a centimeter. The displaced atom is observed directly in the dipole trap by fluorescence detection. The trapping field can also be accelerated to eject a single atom into free flight with well-defined velocities.

Integrated JIT Lot-Splitting Model with Setup Time Reduction for Different Delivery Policy using PSO Algorithm
This article develops an integrated JIT lot-splitting model for a single supplier and a single buyer. In this model we consider reduction of setup time, and the optimal lot size are obtained due to reduced setup time in the context of joint optimization for both buyer and supplier, under deterministic condition with a single product. Two cases are discussed: Single Delivery (SD) case, and Multi...

متن کاملGeneration of Nonclassical States of the Radiation Field in the System of a Single Trapped Atom in a Cavity within the First Order of the Lamb-Dicke Approximation
In this paper, we propose a theoretical scheme for the generation of non-classical states of the cavity field in a system of a single trapped atom via controlling the Lamb-Dicke parameter. By exploiting the super-operator method, we obtain an analytical expression for the density operator of the system by which we examine the dynamical behaviors of the atomic population inversion, the phase-spa...
متن کاملThe structural and density state calculation of B Nitrogen doped silicene nano flake
In this paper, we study the effect of single Boron/Nitrogen impurityatom on electronic properties of a silicene nano flake. Our calculations are basedon density functional theory by using Gaussian package. Here, one Si atom insilicene nano flake substitutes with a Boron/Nitrogen atom. The results show thatsubstitution of one Si atom with single Boron/Nitrogen atom increases distanceof impurity ...
