Electron Temperature and Electron-Electron Scattering Length in GaAs/AlGaAs Using Mesoscopic Multiparallel Aperture Geometries
Arati Thapa, Rishav Khatiwada, Prakash Sharma +5
Quantifying electron temperatures and electron-electron scattering lengths is essential for understanding electron transport regimes in two-dimensional systems. To that end, this w…
Cascade of fractional quantum Hall states in 2D system
Zhimou Chen, Jiaojie Yan, Yuxuan Zhu +11
The observation of the fractional quantum Hall (FQH) effect in 2D electron gases ushered in investigations of topological phases driven by strong electron correlations. Their remar…
Observation of e/4 charge at in GaAs
Tomer Alkalai, Emily Hajigeorgiou, Adbhut Gupta +9
Even-denominator fractional quantum Hall states (FQHSs) fall outside the standard Laughlin's and Jain's odd-denominator hierarchy. In this work, we study the FQHS in the lo…
Controlled Switching of Bose-Einstein Condensation in a Mixture of Two Species of Polaritons
Hassan Alnatah, Shuang Liang, Qiaochu Wan +5
We report temperature-dependent switching between lower and upper polariton condensation in a GaAs/AlGaAs microcavity when both of these species have comparable populations in a mi…
Topological Protection in a Landau Flat Band at , a Candidate Filling Factor for Unconventional Correlations
Waseem Hussain, Haoyun Huang, Loren N. Pfeiffer +3
Strong interactions in Landau flat bands are known to stabilize correlated states that do not form in other types of flat bands. We report hallmarks of topological protection at th…
Fractional quantum Hall state at with energy gap up to 6 K, and possible transition from one- to two-component state
Siddharth Kumar Singh, Chengyu Wang, Adbhut Gupta +3
The fractional quantum Hall state (FQHS) observed in the lowest Landau level at filling factor in wide quantum wells has been enigmatic for decades because the two-dimensio…
Mirror-mediated long-range coupling and robust phase locking of spatially separated exciton-polariton condensates
Shuang Liang, Hassan Alnatah, Qi Yao +7
Lattice arrays are valuable simulators for complex mathematical problems, but physical systems typically allow only short-range coupling. We demonstrate a method for independently…
Strong coupling of polaritons at room temperature in a GaAs/AlGaAs structure
Hassan Alnatah, Shuang Liang, Qiaochu Wan +7
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…
Design and Fabrication of Robust Hybrid Photonic Crystal Cavities
Alex Abulnaga, Sean Karg, Sounak Mukherjee +4
Heterogeneously integrated hybrid photonic crystal cavities enable strong light-matter interactions with solid-state, optically addressable quantum memories. A key challenge to rea…
Targeted Polariton Flow Through Tailored Photonic Defects
Elena Rozas, Yannik Brune, Ken West +6
In non-Hermitian open quantum systems, such as polariton condensates, local tailoring of gains and losses opens up an interesting possibility to realize functional optical elements…
Quantum coherence of a long-lifetime exciton-polariton condensate
Yannik Brune, Elena Rozas, Ken West +6
In recent years, quantum information science has made significant progress, leading to a multitude of quantum protocols for the most diverse applications. States carrying resources…

Hassan Alnatah, Qi Yao, Qiaochu Wan +5
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.…
Measurement of exciton fraction of microcavity exciton-polaritons using transfer-matrix modeling
Jonathan Beaumariage, Zheng Sun, Hassan Alnatah +9
We present a careful calibration of the exciton fraction of polaritons in high- (), long-lifetime ( ps), GaAs/AlGaAs microcavities.This is a crucial para…
