铁磁XXZ链的大自旋渐近性

The large-spin asymptotics of the ferromagnetic XXZ chain

Tom Michoel, Bruno Nachtergaele

摘要:

我们提出了新的结果,并给出了一个简明的回顾最近以前的结果上的渐近性的铁磁XXZ海森伯链的低位谱与扭结边界条件的大自旋。我们的主要兴趣是获得这个模型的界面基态的详细信息,以及它们上面的低激发。新的和最详细的结果是使用严格的玻色化版本,这可以解释为量子中心极限定理。

英文摘要:

We present new results and give a concise review of recent previous results on the asymptotics for large spin of the low-lying spectrum of the ferromagnetic XXZ Heisenberg chain with kink boundary conditions. Our main interest is to gain detailed information on the interface ground states of this model and the low-lying excitations above them. The new and most detailed results are obtained using a rigorous version of bosonization, which can be interpreted as a quantum central limit theorem.
