    摘要: 近年來，人們發現諸多的新興材料如強交叉關聯過度金屬氧化物、電磁超穎材料和自旋電子學奈米材料等呈現各種十分有趣的新奇現象如電-磁耦合、負折射、龐大磁晶異向能和量子自旋霍爾效應等，從而造就了許多激動人心的應用前景。人們唯有充分理解新興材料中發生的新奇現象才能在應用上充分利用這些新興材料的異常性質。量子力學計算和古典電磁模擬是探討新興材料新穎性質、尋找和設計具新功能新興材料不可或缺的工具。在本三年計劃期間，主持人及他領導的計算固態物理團隊擬通過大量的量子計算和電磁模擬來探討、發現新興材料的異常性質的起因和機理，並和台灣的實驗科學家合作，力爭在新興材料物理的一些重點課題上有所突破。本三年計劃擬著重研究於下列三類新興材料：(1) 強交叉關聯的過度金屬氧化物如BiMnO3、Li(Na)Cu2O2、Co3Mn2O9等，(2)電磁超穎材料和(3)自旋電子學奈米材料如過度金屬奈米線、摻雜石墨烯和拓樸絕緣體薄膜等。
    In recent years, emergent materials, such as cross-correlated transition metal oxides, electromagnetic metamaterials and spintronic nanomaterials, are found to exhibit a number of fascinating phenomena such as magneto-electric effect, negative refraction, giant magnetic anisotropy energy and quantum spin Hall effect, and thus to have exciting opportunities for technological applications. In order to exploit these novel phenomena for various applications, one should thoroughly understand the mechanisms that control the physical properties of the emergent materials. Quantum mechanical computation and classical electromagnetic simulations are an indispensable and powerful method for investigating the novel properties of materials. In this three-year proposal, we will carry out computational studies of the emergent materials in order to unravel the origin and mechanism of the fascinating phenomena occurring in them. We will also work closely with the experimental colleagues in Taiwan to tackle a few promising issues in material physics and to strive to make some breakthroughs.
