Arun Bansil

The recent research interests of Professor Bansil have focused on questions concerning the electronic structure and spectroscopy of high-Tc superconductors, topological insulators, nanosystems, and other complex materials. Professor Bansil’s group has developed and implemented the theoretical methodology for carrying out first-principles calculations of spectral intensities relevant for angle-resolved photoemission, scanning tunneling microscopy/spectroscopy, inelastic x-ray scattering, magnetic and non-magnetic Compton scattering, positron-annihilation angular correlation, among other spectroscopies in systems of the complexity of the high-Tc’s. Theoretical approaches based on the local-density approximation as well as techniques for going beyond this framework to incorporate effects such as strong electron correlations, superconductivity and phonons have been developed to obtain comprehensive spectroscopic modeling schemes. We are also considering how effects of substitutions and dopants on the electronic states can be treated realistically in wide classes of materials. These investigations have yielded, for example, important new insights into the existence of Fermi surfaces, the nature of electronic states near the Fermi energy, as well as the mechanism of superconductivity in the high-Tc’s. We have recently predicted successfully a number of new topological insulator materials through first-principles modeling. Professor Bansil’s research effort involves extensive collaborations with groups within and outside the United States. 活动家作为专业第三方嘉宾邀约平台，依托互联网公开数据为您提供嘉宾信息展示服务。若您发现嘉宾信息需要更新或移除，请发送邮件或联系客服。 我们专注于根据您的具体需求（包括演讲议题、会议日期及活动预算等），为您精准匹配各领域专业嘉宾。 为高效服务，建议您提前准备好详细活动信息，并拨打客服电话：18911802888（工作日9:00-18:00）。 温馨提示：本服务仅限嘉宾邀约相关事宜，其他需求暂不处理，感谢您的理解与配合。
