從事凝聚態理論研究工作,在強關聯電子系統、高溫超導、介觀輸運,非線性系統及數值計算方法的發展及套用等方面共發表40餘篇SCI文章, 其中物理專業頂級期刊Phys. Rev. Lett.文章5篇。與人合作,較有代表性的工作有:在國際上較早開展與時間相關的密度矩陣重正化群的研究,提出數值精確處理非平衡態輸運的新方法;建立電子型摻雜銅基超導體唯象兩帶模型,正確解釋超流密度的低溫行為,解決了該體系的超導配對對稱性的爭論;根據銅基空穴型摻雜超導體電子結構特點,預言c-軸電阻的普適標度行為,並解釋了實驗數據;分析銅基空穴型摻雜超導體正常態大量的輸運實驗數據,提出贗能隙是支配輸運行為重要的能量尺度;建立描述單雜質Anderson模型的Fano共振理論,統一解釋了不同過渡金屬原子在金屬表面的掃描隧道譜實驗;預言了具有自旋軌道耦合的碳納米管量子點系統kondo效應的精細結構。
主持完成國家自然科學基金項目“電子型高溫超導體電子配對對稱性研究”(2005-2007),“關聯動力學在凝聚態及核物理中的套用研究”(2001-2003),參與完成國家自然科學基金重點項目“共軛分子體系電子關聯與激發態研究”(2005-2008)。教育部“優秀青年教師計畫”(2001-2003),入選2006年教育部“新世紀人才計畫”。目前主持國家自然科學基金項目“電子型高溫超導體微觀兩帶模型研究”(2009-2011),參與國家自然科學基金重點項目“密度矩陣重正化群方法及其在關聯量子系統中的套用”(2010-2013)。

研究方向

交叉學科研究中心主要研究方向:
1)強關聯電子系統與高溫超導
2)介觀輸運與動力學控制
3)密度矩陣重正化群算法與套用
4)量子信息與量子光學

研究工作

中心開展的主要工作:
1)銅基高溫超導體的微觀模型研究(實驗與理論的分析計算,很辛苦的工作且需要長期的積累)。 2)Kondo問題研究(自旋的禁止問題,曾或將在很多系統中觀察到。實驗現象豐富,但真正的理論進展並不容易)。
3)量子化學密度矩陣重正化群算法研究和套用(一項從2004年就開始的工作,...)。
4)量子退相干和糾纏動力學(量子信息,量子計算實現之前必須解決的問題 ... )。
5)非自治(或時間相關)量子系統的動力學控制(好像跟現代技術的發展與認識自然和改造自然的理念有關)。
