Quantization through dissipation: impurity states and the optical quantum Hall effect

Zhenisbek Tagay, Ahmed Abouelkomsan, Yugo Onishi +4

The integer quantum Hall effect remains the most paradigmatic and remarkable example of exact quantization in condensed matter physics. Its Hall conductivity is fixed to $…

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…

Observation of even-denominator fractional quantum Hall states at and 5/4 in the lowest Landau level

Siddharth Kumar Singh, Chengyu Wang, Adbhut Gupta +3

Two-dimensional electron systems (2DESs) confined to wide GaAs quantum wells provide a unique platform to study exotic fractional quantum Hall states (FQHSs) because the 2DES has a…

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 Superfluidity and Meissner Effect of Composite Bosons in GaAs Quantum Hall System

Yuanze Li, Renfei Wang, Jiahao Chen +7

The quantum Hall effect (QHE) is theoretically understood as a superfluid condensate of composite bosons (CBs) -- bound states of electrons and magnetic flux quanta. While dissipat…

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…
