Quantum Optics of Correlated Systems
Abstract
Controlling light-matter interactions at the level of single photons and single excitations (e.g., electronic, excitonic, phononic) is crucial in advancing many technologies to the next generation. For example, strong light-matter interactions are expected to play a crucial role in next-generation optoelectronic technologies for sensing, optical communication, and advanced computing. In the past several decades, there have been remarkable advances in solid-state quantum optics. In particular, by controlling photon-electron interaction at the single-excitation level in individual quantum emitters, researchers have developed single- and entangled-photon states and also spin-based quantum memories. While these techniques have been limited to manipulation of single excitations (i.e., single-particle physics), it is intriguing to explore whether these quantum optical control techniques could provide a radically new avenue to prepare, manipulate and detect electronic many-body states. This approach could have direct applications in quantum information sciences and material science, such as sensing, quantum information processing, and high-Tc superconductivity. In this proposal, we investigate quantum optical properties of low-dimensional (1D and 2D) strongly interacting electronics systems. One the one hand, we investigate the underlying nature of light-matter interaction in these systems, e.g. by going beyond the dipole approximation regime, to understand how photons can unambiguously unravel their physical properties of correlated electrons, such as Luttinger liquids and superconducting systems. On the other hand, we explore quantum optical schemes to manipulate such strongly interacting systems to enhance or entirely modify their functionalities. The goal is to create novel quantum photonic and electronic states, with robustness to decoherence and thermal noise.
