Unitarity Schrodinger Equation and Ground State Properties of the Finite Trapped Superfluid Fermi Gases in a BCS-BEC Crossover 下载免费PDF全文
On the basis of quantum hydrodynamical equations we derive a unitarity Schrodinger equation of a finite trapped superfluid Fermi gas valid in the whole interaction regime from BCS superfluid to BEC. This equation is just the Ginzburg-Laudau-type equation for the fermionic Cooper pairs in the BCS side, the Gross-Pitaevskii-type equation for the bosonic dimers in the BEC side, and a unitarity equation for a strongly interacting Fermi superfluid in the unitarity limit. By taking a modified Gauss-like trial wave function, we solve the unitarity Schrodinger equation, calculate the energy, chemical potential, sizes and profiles of the ground-state condensate, and discuss the properties of the ground state in the entire BCS-BEC crossover regimes. 相似文献

随着人类社会的进步,经济的发展,生活水平的提高,喝什么样的水有益健康逐步成为人们越来越关心的问题。将我国《生活饮用水卫生标准》与世界卫生组织的《饮用水水质准则》比较,卫生学指标的要求大体相同。有毒有害物质的指标要求大体相同。矿泉水和城市自来水是首选的健康饮水。 相似文献
