Strong coupling of polaritons at room temperature in a GaAs/AlGaAs structure Open

Hassan Alnatah, Shuang Liang, Qiaochu Wan, Jonathan Beaumariage, Ken West , et al. · 2025

We report direct measurement of the dispersion relation of polaritons in GaAs/AlGaAs microcavity structures at room temperature, which clearly shows that the polaritons are in the strong coupling limit. The Rabi splitting of the polariton …

Bose–Einstein Condensation of Polaritons at Room Temperature in a GaAs/AlGaAs Structure Open

Hassan Alnatah, Shuang Liang, Qi Yao, Qiaochu Wan, Jonathan Beaumariage , et al. · 2024

We report the canonical properties of the Bose-Einstein condensation of polaritons in the weak coupling regime, seen previously in many low-temperature experiments, at room temperature in a GaAs/AlGaAs structure. These effects include a no…

High Efficiency of Exciton-Polariton Lasing in a 2D Multilayer Structure Open

Yuening Fan, Qiaochu Wan, Qi Yao, Xingzhou Chen, Yuanjun Guan , et al. · 2024

We have placed a van der Waals homostructure, formed by stacking three two-dimensional layers of WS₂ separated by insulating hBN, similar to a multiple-quantum well structure, inside a microcavity, which facilitates the formatio…

Bose-Einstein condensation of polaritons at room temperature in a GaAs/AlGaAs structure Open

Hassan Alnatah, Qi Yao, Qiaochu Wan, Jonathan Beaumariage, Ken West , et al. · 2024

We report the canonical properties of Bose-Einstein condensation of polaritons, seen previously in many low-temperature experiments, at room temperature in a GaAs/AlGaAs structure. These effects include a nonlinear energy shift of the pola…

Bose Condensation of Upper-Branch Exciton-Polaritons in a Transferable Microcavity Open

Xingzhou Chen, Hassan Alnatah, Danqun Mao, Mengyao Xu, Yuening Fan , et al. · 2023

[Image: see text] Exciton-polaritons are composite quasiparticles that result from the coupling of excitonic transitions and optical modes. They have been extensively studied because of their quantum phenomena and potential applications in…

Bose condensation of upper-branch exciton-polaritons in a transferrable microcavity Open

Xingzhou Chen, Hassan Alnatah, Danqun Mao, Mengyao Xu, Qiaochu Wan , et al. · 2023

Exciton-polaritons are composite bosonic quasiparticles arising from the strong coupling of excitonic transitions and optical modes. Exciton-polaritons have triggered wide exploration in the past decades not only due to their rich quantum …

Charged Bosons Made of Fermions in Bilayer Structures with Strong Metallic Screening Open

Zheng Sun, Jonathan Beaumariage, Qiaochu Wan, Hassan Alnatah, Nicholas Hougland , et al. · 2021

Two-dimensional monolayer structures of transition metal dichalogenides (TMDs) have been shown to allow many higher-order excitonic bound states, including trions (charged excitons), biexcitons (excitonic molecules), and charged biexcitons…

Charged bosons made of fermions in a solid state system without Cooper pairing Open

Zheng Sun, Jonathan Beaumariage, Qiaochu Wan, Hassan Alnatah, Nicholas Hougland , et al. · 2020

We report experimental evidence for charged boson states in a solid without Cooper pairing, based on attaching two free carriers to an exciton in a semiconducting system. Theoretical calculations show that this type of complex is stable in…
