Optimal Conditions for Atomic Homodyne Detection on Bose-Einstein Condensates [PDF]

open access: yes, 2006
The dynamics of a two-mode Bose-Einstein condensate trapped in a double-well potential results approximately in an effective Rabi oscillation regime of exchange of population between both wells for sufficiently strong overlap between the modes functions.

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

Atomic Parity Non-Conservation, Neutron Radii, and Effective Field Theories of Nuclei [PDF]

open access: yes, 2005
Accurately calibrated effective field theories are used to compute atomic parity non-conserving (APNC) observables. Although accurately calibrated, these effective field theories predict a large spread in the neutron skin of heavy nuclei.
