2021 MRS Fall Meeting: Symposium NM03 - Topological and Quantum Phenomena in Intermetallic Compounds and Heterostructures

非技术性总结：2021年虚拟材料研究学会会议（2021年4月17日至23日）的研讨会“NM 03：金属间化合物和异质结构中的拓扑和量子现象”为处于职业生涯不同阶段的科学家提供了一个跨学科的场所，以分享他们的研究并建立新的合作。这是MRS会议上关于这一主题的第一次跨学科研讨会，吸引了在材料科学，化学，物理和电气工程方面接受过培训的科学家。为期两天的虚拟研讨会有48个口头报告，其中29个是特邀演讲者。受邀演讲者中有11位是女性，9位是非终身制的初级教师或博士后。演讲者来自世界各地，包括北美，欧洲，亚洲和中东。材料研究部的固态与材料化学项目和凝聚态物理项目的支持促进了学生、博士后研究人员和初级教师的参与。技术总结：金属间化合物具有广泛的量子、拓扑和多铁性现象，包括手性自旋织构、外尔态和狄拉克态、新型超导性、重费米子行为、铁弹性和磁热行为。这种多样的性能范围可以与经过充分研究的过渡金属氧化物相媲美;然而，在控制化学计量和缺陷，制造原子级精确界面以及表征基本电子和磁性结构方面仍然存在突出的挑战。本次研讨会汇集了专家，探讨各种金属间化合物家族的共同主题，包括Heusler化合物，腔隙尖晶石，Weyl半金属，稀土化合物，skyrmion化合物等。该研讨会由材料研究部的固态和材料化学计划和凝聚态物理计划支持，突出了体晶和外延膜生长，先进表征，材料预测/设计，该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识产权进行评估来支持。优点和更广泛的影响审查标准。

Non-technical summary:The symposium “NM03: Topological and Quantum Phenomena in Intermetallic Compounds and Heterostructures” at the 2021 Virtual Materials Research Society Meeting (April 17-23, 2021) provides an interdisciplinary venue for scientists at varying stages in their careers to share their research and establish new collaborations. It is the first interdisciplinary symposium on this topic at an MRS Meeting, drawing on scientists with training in Materials Science, Chemistry, Physics, and Electrical Engineering. The two-day virtual symposium features 48 oral presentations, of which 29 are invited speakers. 11 of the invited speakers are female and 9 are untenured junior faculty or postdocs. Speakers are drawn from all over the world, including North America, Europe, Asia, and the Middle East. Support by the Solid State and Materials Chemistry program and the Condensed Matter Physics program in the Division of Materials Research facilitates the participation of students, postdoctoral researchers, and junior faculty.Technical summary:Intermetallic compounds host a broad range of quantum, topological, and multiferroic phenomena, including chiral spin textures, Weyl and Dirac states, novel superconductivity, heavy fermion behavior, ferroelasticity, and magnetocaloric behavior. This diverse range of properties rivals that of the well-studied transition metal oxides; however, outstanding challenges remain in controlling stoichiometry and defects, fabricating atomically precise interfaces, and characterizing the fundamental electronic and magnetic structures. This symposium brings together experts to explore common themes across the various families of intermetallics, including Heusler compounds, lacunar spinels, Weyl semimetals, rare earth compounds, skyrmion compounds, and others. The symposium, support by the Solid State and Materials Chemistry program and the Condensed Matter Physics program in the Division of Materials Research, highlights recent advances in bulk crystal and epitaxial film growth, advanced characterization, materials prediction/design, and new device concepts for intermetallic compounds.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
