重离子碰撞中的玻色-爱因斯坦凝聚:有限体积修正的重要性和不确定性

Bose-Einstein condensation in heavy ion collisions: importance of and uncertainties in the finite volume corrections

Kacper Zalewski

摘要:

本文计算了在三种边界条件下,在给定温度和(平均)总π介子密度的情况下,立方盒子中无相互作用π介子的玻色-爱因斯坦凝聚体的密度。密度比热力学预测的大得多,并且显著地取决于边界条件的选择,甚至对于像$6.4\cdot 10$ fm $^3$那样大的体积也是如此。

英文摘要:

The density of the Bose-Einstein condensate for non-interacting pions in a cubic box, at given temperature and (average) total pion density, is calculaated for three sets of boundary conditions. The densities are much larger than predicted from thermodynamics and depend significantly on the choice of the boundary conditions, even for volumes as large as $6.4\cdot 10$fm$^3$.
