Modern condensed matter physics is to discover and realize novel physical properties, embracing three central themes - strong correlation, low dimen-sionality, and topology. Although these topics were traditionally regarded separate, it is recently being recognized that they are all intertwined in “quantum materials.”

So far, a majority of research has focused on "finding" quantum materials with novel properties. Herein, we take a rather unique approach to devise a new platform and realize exotic phenomena, manipulating spatio-temporal parameters. For example, combining different materials into ultrathin film heterostructures leads to unprecedented phenomena via quantum inter-ference between them, and harnessing nonlinear optics leads to modifi-cation of electronic structure of the quantum material. Employing this unique approach and leveraging our expertise, we aim to accomplish challenging yet feasible objectives
