“…Alternatively, Grigoryan and Xia have proposed an approach to explore level attraction [28] in hybrid magnon-photon systems, by modulating the relative phase [29] between coherent microwaves, and very recently Boventer et al [30] reported level attraction in these systems. Due to its potential applications in topological energy transfer, quantum sensing, and nonreciprocal photon transmission, level attraction has been of great interest in studies of other systems, such as in Bose-Einstein condensated quantum systems [31,32], microcavity polariton systems [33] and cavity optomechanical systems [34][35][36].…”

We report on coherent and dissipative coupling between a magnon mode and an anti-resonance of transmission in a cylindrical microwave cavity. By effectively suppressing coherent coupling, we observe the hybridized dispersion to change from level repulsion to level attraction. A careful examination reveals distinct differences in the line shape and phase evolution of transmission spectra between these coupling behaviors. For a quantitative understanding of the interactions between the magnon mode and the cavity anti-resonance, we develop a model which precisely describes our experimental observations, particularly, the signature in the line shape and phase of the microwave transmission. Our work sets a foundation for understanding strong coupling between magnon modes and cavity anti-resonances. In addition, it also confirms the ubiquity of level attraction in coupled magnon-photon systems, which may be helpful to develop future magnon-based hybrid quantum systems.

“…Next, we measured the spectral responsivity of our near-field plasmon detectors. Our hybrid devices contain two constituent elements with distinct spectral inverted band dispersion for the lowest trion derived branch [204]. These results suggests an interesting route for studying many -body physics and interesting devices based on cavity polaritonics [205,49,206,207].…”

Let us begin our journey by revisiting some of the history and fundamental properties of flatland materials-materials that are two-dimensional. In this chapter we will introduce the different types of two dimensional (2D) materials that we have studied in this work. We will also discuss some of the techniques of preparation and identification of these materials. Finally, a brief overview of the thesis will be presented.

“…Strong coupling between photons with both excitons and trions was also observed . Such a coupling leads to the observation of multiple cavity polariton resonances (labeled as UPB, MPB, and LPB in Figure f) by angle‐resolved PL spectroscopy at cryogenic temperatures.…”

Exciton polaritons (EPs) are half‐light, half‐matter quasiparticles formed due to the coupling between photons and excitons in semiconductors. Their uniqueness lies at the strong light–matter interactions and long‐distance transport, thus promising for many novel applications in photonics, information, and quantum technologies. Recently, EPs in group‐VI transition‐metal dichalcogenides (TMDs) have attracted a lot of research interest due to their room‐temperature stability, long‐distance propagation, and controllability through electric gating, valley‐selective optical pumping, and precise thickness control. In this progress report, recent studies of EPs in TMDs are reviewed, highlighting their key properties and functionalities, and then discussing the potential directions for future research.
