粗粒化核相互作用
Coarse graining Nuclear Interactions
摘要：
我们认为，在坐标空间中的NN相互作用的粗粒度非常著名的Vlowk方法的精神。为此，我们采样的相互作用在最小德布罗意波长探测NN散射低于π生产阈值。这相当于提供了一个简单的δ壳层电势加上2 fm以上的标准OPE电势。讨论了核多体问题中可能的简化。
英文摘要：
We consider a coarse graining of NN interactions in coordinate space very much in the spirit of the well known Vlowk approach. To this end we sample the interaction at about the minimal de Broglie wavelength probed by NN scattering below pion production threshold. This amounts to provide a simple delta-shell potential plus the standard OPE potential above 2 fm. The possible simplifications in the Nuclear many body problem are discussed.
