ELECTROMAGNETIC FIELD SENSING THROUGH SUPERRADIANCE IN 2D MATERIALS
Abstract
This project aims at devising novel sensing modalities of electromagnetic waves using 2D materials and collective coherent quantum emission, superradiance. Superradiance is the cooperative enhancement of radiation by an ensemble of closely packed emitters that are coupled to the same photonic field. Superradiance is characterized by a short intense burst of coherent emission whose intensity scales by the square of the number of contributing emitters, in contrast to a linear scaling with the number of emitters in the uncoupled case. The corresponding superradiant states lead to a plethora of unique features that do not have classical equivalents and unique advantages for quantum-enhanced sensing. However, superradiance studies so far have barely gone beyond the mere demonstration of the phenomenon, and its use in sensing has largely remained unexplored. This project will combine the promise of superradiance with the unique properties of 2D materials to provide fundamental insights into this largely unexplored area with two overarching goals: (1) to understand coherent collective processes in 2D materials, and (2) based on this new knowledge, to develop novel electromagnetic sensing modalities with unparalleled performance. Specifically, this project will develop a designer’s materials approach with precise atomic-scale engineering to understand and control superradiance from 2D materials, and explore electric field sensing via the giant Stark shift induced in 2D superradiance. Exquisite sensitivity is anticipated due to the ultra-narrow linewidth and ultra-low noise of 2D superradiance. This study will revolutionize current understanding of collective coherent emissions, and guide the design of 2D systems for superradiance-related applications. Key innovations, including fundamentally new methods to manufacture quantum emitters and ultra-sensitive electrometers, will broadly benefit the fields of nanomaterials, quantum technology, and electromagnetic sensing.
