MSE Seminar: “Topological Quantum Phases, Novel Superconductors, and Ultra-Thin Films Beyond Graphene”
December 9, 2021 at 12:30 PM - 1:30 PM
Dr. Bansil will discuss some of his recent work aimed at understanding the electronic structure and spectroscopy of novel superconductors, topological materials, and atomically thin 2D films and battery materials. [1-5] Illustrative examples will include: (i) How by exploiting electronic structure techniques we have been able to successfully predict and understand the characteristics of many new classes of topologically interesting materials, including magnetic topological materials; (ii) How atomically thin beyond graphene 2D and layered materials offer exciting new possibilities for manipulating electronic structures and provide novel platforms for fundamental science studies and applications; And, (iii) with regard to the high-Tc’s, he will discuss recent breakthroughs in modeling the insulating pristine compounds and their transition from the insulating to the metallic state with doping without invoking free parameters such as the Hubbard U parameter. A first-principles description of the competing stripe and magnetic phases in the cuprates also then becomes possible, providing a new pathway for modeling correlated materials more generally.
