Title: Harnessing Light-Matter interactions

Abstract

The development of functional materials and device architectures is central to emerging quantum telecommunication technologies. Integrating condensed matter systems with photonic platforms offers a powerful route to engineer new functionalities, while simultaneously improving efficiency and scalability beyond the limits of conventional electronics. In this talk, I will present a research program centered on hybrid light-matter platforms that explores their potential in novel electro-optic applications. I will focus on condensed matter systems where collective excitations and nonlinearities naturally emerge from nontrivial electronic correlations and lattice symmetries. These systems exhibit unconventional electromagnetic responses that, when integrated with circuit quantum electrodynamics (c-QED), enable the formation of unique light-matter states. I will highlight how both passive and active c-QED networks offer scalable routes toward enhanced sensing and amplification, controlled dynamics, and coherent signal transduction between electronic and photonic degrees of freedom. By bridging condensed matter physics and optics, I outline a path toward experimentally accessible quantum phenomena and the development of advanced photoelectric functionalities.
