课题组新闻/Group News



  • 我组今年年初发表在Physical Review B (2020, 101: 155117)上的论文“Bulk Fermi surface of the layered superconductor TaSe3 with three-dimensional strong topologicalstate”报道了通过强磁场磁输运及理论计算揭示的在准一维层状超导体TaSe3中存在强拓扑绝缘态 及非平庸拓扑表面态,并且存在自旋-动量锁定的螺旋表面态,预言其为可能的拓扑超导候选材料。我组博士生夏威(现为拓扑物理实验室博士后)为论文第一作者。近日,通过与我院陈宇林/柳仲楷开展角分辨光电子能谱合作测量,证实了其能带的拓扑结构及拓扑表面态,详见我院关于此进展的报道。链接:https://spst.shanghaitech.edu.cn/2020/1022/c2089a56745/page.htm

  • 2020年9月29日,美国化学会杂志Chemistry of Materials (IF =9.567,2020, 32: 8781.)在线发表了我组博士生 刘晓磊和于振海博士共同一作的文章“High-Pressure Crystal Growth, Superconducting Properties, and Electronic Band Structure of Nb2P5”,介绍了课题组利用高压合成手段,在补偿半金属NbP2菱形三棱柱中沿着b轴(如下图)嵌入了一条无限长的P链,成功诱导了转变温度为2.6 K的第II类超导,其能隙具有s波对称性。第一性原理计算表明,Nb2P5能带结构中由于能带翻转可能形成了非平庸拓扑节线结构,因此有望作为拓扑超导候选材料。恭喜晓磊、振海!

  • 2020 年9月1日,欢迎栗中杨、陶咨成、范晨鑫三位同学加入课题组。


  • 2020 年8月5日,张高宁同学顺利通过硕士论文答辩。恭喜张高宁!


  • 2020 年6月30日,葛雯娜博士顺利通过博士后出站答辩。恭喜葛雯娜!


  • 2020年6月16日,我组与复旦大学李世燕教授课题组合作,发现在较低压力下(< 1 GPa)压力下,拓扑节线半金属SrAs3表现出压力诱导的Lifshitz相变。在较高压力下(~ 23 GPa),出现由压力诱导的单斜到简单立方的结构相变,并伴随出现Tc 最高可达5.8 K的超导电性。经第一性原理计算揭示,简单立方SrAs3为拓扑晶体绝缘体并具有动量-自旋锁定的非平庸拓扑表面态。该结果提供了研究压力诱导拓扑相变及超导与非平庸拓扑相互作用的重要材料,结果发表在新锐杂志npj Quantum Materials (第一个 IF = 6.562。2020,5: 38)。夏威为本论文共同第一作者。


  • 毕业季·物质师生说夏威:专注坚持,启帆远航(https://spst.shanghaitech.edu.cn/2020/0714/c2089a54049/page.htm)。


  • 2020年5月26日,王洪远、夏威同学顺利通过博士论文答辩。恭喜两位同学!


  • 课题组与上海大学理学院马国宏教授课题组合作,在准二维磁性半导体材料CrSiTe3中发现了极强的太赫兹辐射,研究结果以Terahertz emission on the surface of a van der Waals magnet CrSiTe3为题发表于国际著名期刊 Laser & Photonics Reviews(IF = 10.655。 2020, 2000025)

  • 夏威同学发表在Applied Physics Letter(2020, 116: 142103)上的论文The de Haas-van Alphen quantum oscillations in a three-dimensional Dirac semimetal TiSb2”报道了新三维Dirac半金属TiSb2的磁性量子振荡性质及电子能带结构,被选为当期封面论文。

  • 苏豪发表在APL Materials(2020,8:011109)上的论文“Magnetic exchange induced Weyl state in a semimetal EuCd2Sb2”报道了通过利用外磁场调控自旋方向,从而诱导拓扑相变,使得反铁磁拓扑绝缘体转变为铁磁外尔半金属。该工作被选为编辑推荐论文(Edotor's pick)。

  • 刘晓磊学作为共同第一作者发表在Physical Review B (2020, 101: 155114)上的论文“Direct observation of six-fold exotic fermions in topological semimetal PdSb2报道了实验证实无手性新型六重费米子,被选为编辑推荐(Editor's suggestion)。


  • 知名学术杂志《ACS Nano》在线发表了我组与上海科技大学物质学院薛加民以及上海技术物理研究所胡伟达课题组合作完成的研究论文,题为“Nb2SiTe4: A Stable Narrow-Gap Two-Dimensional Material with Ambipolar Transport and Mid-Infrared Response”,报道了发现一种新型窄带隙二维材料。我组夏威同学为论文共同第一作者。

 

  • 我组与物质学院助理教授李刚、柳仲楷研究团队通力合作,成功揭示了在低维量子体系CrSiTe3中电子关联所扮演的重要角色,首次明确地指出了该体系中的电子能隙主要源于电子关联。该项工作近日以“Unveiling Electronic Correlation and the Ferromagnetic Superexchange Mechanism in the van der Waals Crystal CrSiTe3”为题在国际顶尖物理杂志《Physical Review Letters》发表。
