研究领域及成果

学术兴趣:新型拓扑量子态;介观物理;自旋电子学;强关联物理。

近10年,本人从事凝聚态理论的一些前沿课题的研究。具体来说,本人在半导体系统的自旋霍尔效应、石墨烯的电子结构和输运性质、拓扑绝缘体、以及一些强关联系统的超导和磁性性质等课题上进行了研究,并取得了一些有意义的研究成果。对这些年(获得博士学位之后)的研究经历/成果,简要叙述如下(参考“发表论文”条目):

1.我们首先提出和研究的半导体边界自旋--轨道耦合模型(见“发表论文”[17],下同),得到了国际上一些同行的关注,至今被引用了26次。在Nature Nanotechnology、Applied Physics Letters等杂志有相关的实验报道。

2.我们首先分析了石墨烯中的d+id’型超导配对态的低能有效形式,并对各种超导配对态的Andreev电导谱进行了比较研究[11]。论文自08年发表以来,被引用20次,其中两次被Rev.Mod.Phys正面引用。目前graphene中的d+id’型超导配对态已被多种解析和数值结果(如QMC)支持。

3.我们提出用悬空石墨烯体系的共振力电耦合来实现石墨烯体系中的电荷泵浦效应[4]和纯谷(valley)自旋泵浦效应[2],论文先后在Nano letters(2012年)和Phys.Rev.Lett(2013年)发表,在石墨烯valleytronics的研究中提出了新的可行性思路。我们设想的探测纯谷自旋流的纯电学方案,实验上非常方便实现。这个工作正引起一些实验组的关注。

4.给出了二维(三维)拓扑绝缘体边缘态(表面态)的连通性质的一般性证明[7],为拓扑表面态的性质提供了一个基本的理解。

5.在slave-particle框架下,建立了一套针对三角格子t-J模型的平均场理论[18],得到有关三角格子体系超导和磁性性质的一系列富有启发性的结果。

6.用第一性原理计算(VASP软件)的方法,系统地研究了两层和三层Zigzag型石墨烯纳米带的磁性和结构不稳定性[9]。
7.与Purdue大学的实验小组合作,对单、双层复合的石墨烯系统的量子霍尔效应进行了研究[1],我们完成了理论解释部分的工作。

8.在方法层面,本人根据介观物理中的Landauer-Buttiker公式的精神,实现了用散射波函数法严格求解任意多端格子模型中的非平衡物理量(如自旋密度、电流密度等)的计算方法[14,16,17],被PRB审稿人认为是Landauer-Buttiker理论的一个“reasonable extrapolation”。进而,我们证明了它与文献上更加常用的Keldysh非平衡Green函数法等价[28], 但散射波函数法在分析问题的对称性时具有某些优势[14]。

9.此外,本人参与了石墨烯带的自旋相关输运性质[3,5](使用结合第一性&非平衡Green函数的ATK软件)、铁基超导体的超导配对对称性[6](利用严格对角化方法)、石墨烯带和碳纳米管的能谱结构[10,12]、Anderson 拓扑绝缘体[8](非平衡Green函数方法)、高温超导STM谱分析[15](变分Monte Carlo方法)等相关课题的研究工作。

Research Field and Achievements

1. novel topological quantum phases;

2. mesoscopic physics;

3. spintronics;

4. strongly correlated physics.

I’ve been working on some frontier fields in condensed matter physics during the past 10 years(after having obtained my PHD degree in 2002). The research topics include spin hall effect in semiconductor, electronic and transport property in graphene and topological insulator, as well as superconductivity and magnetism of some strongly correlated systems. In the following, I’ll summarize my research activities and  achievements during this period (refer to the numbered items in the section “publication” in the last pages of this CV): 

1.We first proposed and analyzed the edge-confinement-induced spin-orbital coupling model for 2D semiconductor system[17]. This work has 26 citations up to now, among which there are two related experimental works reported in Nature Nanotechnology and Applied Physics Letters.

2.We proposed the concept of effective pairing in the superconducting states of graphene, especially for the state with d+id’ pairing symmetry[11]. We also compared Andreev conductance for various superconducting states[11]. This work has 20 citations, twice by Review of Modern Physics. Now the d+id’ pairing symmetry  was supported by various numerical calculations.  

3.We proposed theoretically a quantum pumping devise based on suspended graphene, which forms an electromechanical resonator.  Such device can function as electron pumping device[4] as well as valley pumping device[2]. We also proposed an all-electrical scheme to detect pure valley current, which has attracted attentions of some experimental groups. These two works were cited around 20 times since 2012.

4. Based on the Landauer-Buttiker picture of mesoscopic transport, we constructed a general approach to solve scattering wave function and calculate nonequilibrium local quantities in arbitrary multi-terminal lattice models. With this approach, we studied spin transport property of various semiconductor 2DEGs[14,16,17]. Such an approach is regarded as a “reasonable extrapolation” of Landauer Buttiker theory(according to referee’s comments) and is later proved[28] to be equivalent to Landauer-Keldysh Green’s function approach adopted by other groups. However, it’s especially useful in symmetry analysis of transport problems[14].

5.We provided an exact proof for the connectivity property of edge(surface) states of 2D(3D) topological insulators with time reversal symmetry[7].

6.We studied the strong correlated t-J model for triangular lattice in the framework of slave-particle with proper mean field ansatz. The magnetic phase diagram is systematically discussed. The spin dynamics of possible d+id’ superconductivity state is analyzed[18].

7.Using the famous software VASP to do first principle calculation, we studied the magnetic and structural instability of zigzag-edged bi-layer and tri-layer graphene nanoribbon[9]. This work has been cited 13 times since 2011. 

8.We measured and analyzed the transport property of monolayer-bilayer hybrid graphene structure under strong magnetic field[1].

9. Besides, I also take part in some other projects such as spin transport of graphene nanoribbon[3,5](using the ATK software which combined first principle calculation and nonequilibrium green’s function), study of superconducting pairing symmetry of  iron-based superconductors[6](exact diagonalization), energy spectrum of graphene nanoribbon and carbon nanotube[10,12], STM spectrum analysis for high Tc superconductor[15](variational Monte Carlo) and Anderson topological insulator[8], etc.
