报告人简介：

Prof. Antonio Bianconi graduated from the University of Rome with a PhD degree in Physics. In 1987, he identified Cu 3d9 L-ligand holes of HTS for the first time. He used scanning nanoscale X-ray diffraction to discover nanoscale phase separation in interstitial oxygen doped cuprates, iron-based pnictides, iron-based chalcogenides. In 2015 he provided evidence for percolating pathways of interface-superconductivity with a power-law Levy distribution in superconductors at optimal doping. He has been working at Stanford University, Camerino University, Paris Sorbone University, L’Aquila University, Mephi University, and Rome University. Now he is the director of the Rome International Center Materials Science and the Senior researcher at Consiglio Nazionale delle Ricerche, Institute of Crystallography. He has been the chairman of the series of Stripes and Superstripes Conferences since 1996. He is a Fellow of the American Physical Society, a Foreign member of the Latvian Academy of Sciences, a Member of the European Academy of Sciences, and Editor-in-Chief of the Journal Condensed Matter. He won the Price for excellent contributions to X-ray absorption spectroscopy which is awarded by the International X-ray Absorption Society (IXAS).

报告摘要：

Artificial high Tc superlattices (AHTS) made by quantum design showing superconductivity controlled by nanoscale lattice heterogeneity via Fano Feshbach resonance. At 38 years after the discovery of high Tc superconductivity (HTS) in natural copper oxide perovskites we report first-principles quantum material design of the optimal topology of artificial 2-5 nm heterostructures making it possible to shed light on the mechanism of HTS. We present a practical application of the theory of the superconducting multiple gaps superconductivity in quantum nanostructured materials where quantum geometry controls quantum functionality. Advances in few-nm technology make it feasible to verify theory predictions by synthesis of artificial superlattices of quantum wells controlling the spin-orbit coupling (SOC) due to the internal electric field in interface superconductivity and tuning the system at unconventional Lifshitz transitions in nanoscale superlattices.
