Note: Sometimes high … WebApr 12, 2024 · We measure the momentum density in a Bose-Einstein condensate (BEC) with dilute spin impurities after an expansion in the presence of interactions. We observe tails decaying as 1 / k 4 at large momentum k in the condensate and in the impurity cloud. These algebraic tails originate from the impurity-BEC interaction, but their amplitudes … WebHence, dilute impurity doping provides a rational pathway for designing thermally robust and high-performance GeTe-based alloys. In this regard, phase diagram engineering probes the leverage between the diffusion-driven spinodal ... The dilute-alloying (PbTe)0.05(GeTe)0.95 stalachtis phlegia
