有机polymer二甲氨基吡咯的自旋密度泛函研究:有机周期Anderson模型的实现

Spin-density functional study of the organic polymer dimethylaminopyrrole: A realization of the organic periodic Anderson model

Yuji Suwa, Ryotaro Arita, Kazuhiko Kuroki, Hideo Aoki

摘要:

虽然周期性安德森模型(PAM)已被公认为各种重f-电子系统的一个很好的模型,在这里,我们设计了一个纯有机聚合物,其低能物理可以被PAM捕获。通过自旋密度泛函计算,我们表明,二甲基氨基吡咯聚合物是一个候选者,它的基态确实可以磁性依赖于掺杂。讨论了有利于铁磁基态的因素。

英文摘要:

While the periodic Anderson model (PAM) has been recognized as a good model for various heavy f-electron systems, here we design a purely organic polymer whose low-energy physics can be captured by PAM. By means of the spin density functional calculation, we show that polymer of dimethylaminopyrrole is a candidate, where its ground state can indeed be magnetic depending on the doping. We discuss the factors favoring ferromagnetic ground state.
