BCS-么正性交叉中费米超流体的普适标度

Universal scaling in a trapped Fermi super-fluid in the BCS-unitarity crossover

Sadhan K. Adhikari

摘要:

使用数值模拟的基础上的密度泛函方程的被困费米超流体有效沿BCS-么正性交叉,我们建立了强大的缩放超过许多数量级的系统的可观的费米子数的函数。这种缩放允许预测系统的静态特性,例如能量、化学势等,对于大量的费米子,通过交叉,从那些对于少量($\sim 4-10$)费米子的知识。

英文摘要:

Using numerical simulation based on a density-functional equation for a trapped Fermi super-fluid valid along the BCS-unitarity crossover, we establish robust scaling over many orders of magnitude in the observables of the system as a function of fermion number. This scaling allows to predict the static properties of the system, such as energy, chemical potential, etc., for a large number of fermions, over the crossover, from the knowledge of those for a small number ($\sim 4-10$) of fermions.
