教學與研究領域
教學:
本組於2014年2月起開設選修課程:密度泛函理論 (Density Functional Theory)。歡迎有興趣的學生選修。

研究:
"The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation." P. A. M. Dirac (1929)

為了迎接這項挑戰,本組致力於研究能適用於奈米系統(約含100~1,000,000個電子)的新量子理論(如:熱輔助佔據密度泛函理論),並應用其於預測新穎奈米系統(如:莫比烏斯分子、三角形石墨烯奈米片、線狀與環狀碳鏈、線狀與環狀硼奈米帶等)之特性,以及開發新能源材料(如:太陽能電池及儲氫材料等)。

由於奈米科學為跨學科領域研究,需打破傳統的學科領域界限,以取得更具啟發性之成果。
依研究性質分為:
1. 理論研究(新密度泛函理論之發展):以物理學為主,數學與化學為輔。
2. 計算研究(新密度泛函理論之應用):目前所涉及的知識包括物理學、化學與材料科學,並在未來將進一步擴展到其他學科領域(如:生物學與天文學)。
