Summary: Melt quenching is used to create PbO-TeO2-MgO-Na2O-B2O3 glasses with increasing lead concentration leading to increased density and decreased indirect band gap values. The refractive index, optical dielectric constant, and dielectric constant also increase with higher lead content. The partial replacement of B2O3 with PbO compounds affects the shielding characteristics and enhances the linear attenuation coefficient. The fabricated glasses show improved radiation protection efficiency and are recommended for use in radiation zones.

Summary: This work demonstrates how the current phase transition of atomic Bose-Einstein condensates in a trap can be controlled by applying an oscillatory driving field. The self-trapping effect in momentum space allows for a suppression of oscillations and a nearly constant directed current. Mean-field chaos serves as an indicator of the quantum phase transition. These findings are supported by an effective three-mode model.
