Even-odd parity effects in conductance and shot noise of metal-atomic wire-metal(superconducting) junctions

open access: yes, 2002
In this paper, we study the conductance and shot noise in transport through a multi-site system in a two terminal configuration. The dependence of the transport on the number of atoms in the atomic wire is investigated using a tight-binding Hamiltonian ...

A transferable artificial neural network model for atomic forces in nanoparticles

open access: yes, 2018
We have designed a new method to fit the energy and atomic forces using a single artificial neural network (SANN) for any number of chemical species present in a molecular system.

Dopant Concentration and Effective Atomic Number of Copper-Doped Potassium Borate Glasses

open access: yesAdvances in Materials Science and Engineering, 2013
Copper-doped (0.5 mol%) and undoped potassium borate glasses have been prepared by the composition of (100-x)H3BO3 + xK2CO3, where 10 ≤ x ≤ 30 mol % by the traditional melting quenching method. The structural pattern of glasses with different composition

Calculation of effective atomic numbers and electron densities of different types of material for total photon interaction in the continuous energy region via different methods

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2017
Effective atomic number (Zeff) and electron density (Neff) are convenient parameters used to characterise the radiation response of a multi-element material in the technical and industrial applications, radiation shielding design, absorbed dose and ...

Atomic number fluctuations in a mixture of two spinor condensates

open access: yes, 2010
We study particle number fluctuations in the quantum ground states of a mixture of two spin-1 atomic condensates when the interspecies spin-exchange coupling interaction $c_{12}\beta$ is adjusted.

Entanglement between photons and atoms coupled out from a Bose-Einstein-Condensate [PDF]

open access: yes, 2001
We study the limitations to the relative number squeezing between photons and atoms coupled out from a homogeneous Bose-Einstein-Condensate. We consider the coupling between the translational atomic states by two photon Bragg processes, with one of the ...

Definitive number of atoms on demand: Controlling the number of atoms in a few-atom magneto-optical trap [PDF]

open access: yesApplied Physics Letters, 2006
A few Rb85 atoms were trapped in a micron-size magneto-optical trap with a high quadrupole magnetic-field gradient and the number of atoms was precisely controlled by suppressing stochastic loading and loss events via real-time feedback on the magnetic-field gradient. The measured occupation probability of a single atom was as high as 99%.
