    NSLS-II Colloquium

    "Programmable quantum materials"

    Presented by Dmitri N. Basov, Columbia University

    4 pm, Large Seminar Room, Bldg. 510

    Thursday, March 12, 2020, 4:00 pm

    Hosted by: John Hill

    Experimentally realizing quantum phases of matter and controlling their properties is a central goal of the physical sciences. Novel quantum phases with controllable properties are essential for new electronic, photonic, and energy management technologies needed to address the growing societal demands for rapid and energy efficient information processing and transduction. Quantum materials offer particularly appealing opportunities for the implementation of on-demand quantum phases. This class of materials host interacting many-body electronic systems featuring an intricate interplay of topology, reduced dimensionality, and strong correlations that leads to the emergence of "quantum matter'' exhibiting macroscopically observable quantum effects over a vast range of length and energy scales. In this talk I will overview recent efforts to discover, characterize and deploy new forms of quantum matter controllable by light, gating, and nano-mechanical manipulation, effectively programming their properties. I will focus on enticing opportunities to investigate novel quantum phenomena using nascent nano-optical methods developed in my group (1,2,3) 1. S. S. Sunku, G. X. Ni, B. Y. Jiang, H. Yoo, A.
