准粒子的热通量和He3-B中turbulence两种态的转变
Thermal flux of quasiparticles and the transition between two regimes of turbulence in He3-B
摘要：
我们计算了He 3-B中热准粒子流入射到各种二维涡旋位形时的Andreev反射系数。我们发现，对于相同数量的正涡点和负涡点，反射系数大大降低，如果点是成对排列（这对应于一个气体的涡环在三维），而不是随机（这对应于一个涡缠结在三维）。这一结果与兰开斯特大学的Bradley等人进行的测量结果一致。
英文摘要：
We compute the Andreev reflection coefficient of a flux of thermal quasiparticles in He3-B incident upon various two-dimensional vortex configurations. We find that, for the same number of positive and negative vortex points, the reflection coefficient is much reduced if the points are arranged in pairs (which corresponds to a gas of vortex rings in three-dimensions) rather than random (which corresponds to a vortex tangle in three-dimensions). This results is consistent with measurements performed by Bradley et al. at the University of Lancaster.
