我肯定哪儿理解错了。 | t*****n 发帖数: 223 | 2 I did something about slave boson in QD systems.
If you use Slave boson numerical method, the kondo peak increase with
temperature, which doesn't make sense.
But if you use numerical RG, kondo peak decrease.
I think it comes from the SBMF.

| x***u 发帖数: 6421 | 3 这就是我的问题啊,slave boson给出的宽度随温度是变窄的,而数值计算象NRG的结果
至少看起来是增加的。我没找到有讨论这个的文献,你知道有什么文献么?

| t*****n 发帖数: 223 | | t*****n 发帖数: 223 | 5 When I was doing SBMF on kondo problem, some expert told me about this.
Then I change to do NRG. So for the reference, I really don't know. |
