Microwave-induced resistance oscillations in a back-gated GaAs quantum well
X. Fu, Q. A. Ebner, Q. Shi +3
We performed effective mass measurements employing microwave-induced resistance oscillation in a tunable-density GaAs/AlGaAs quantum well. Our main result is a clear observation of…
Device Architecture for Coupling Spin Qubits Via an Intermediate Quantum State
X. G. Croot, S. J. Pauka, J. D. Watson +4
We demonstrate a scalable device architecture that facilitates indirect exchange between singlet-triplet spin qubits, mediated by an intermediate quantum state. The device comprise…
Theory of topological excitations and metal-insulator transition in reentrant integer quantum Hall effect
G. E. Simion, T-G. Lin, J. D. Watson +4
The reentrant integer quantum Hall effects (RIQHE) are due to formation of electronic crystals. We show analytically and numerically that topological textures in the charge density…
Quantum Lifetime in Ultra-High Quality GaAs Quantum Wells: Relationship to and Impact of Density Fluctuations
Qi Qian, James R. Nakamura, Saeed Fallahi +6
We consider quantum lifetime derived from low-field Shubnikov-de Haas oscillations as a metric of quality of the two-dimensional electron gas in GaAs quantum wells that expresses l…
High temperature resistivity measured at ν = 5/2 as a predictor of 2DEG quality in the N=1 Landau level
Qi Qian, James R. Nakamura, Saeed Fallahi +3
We report a high temperature (T = 0.3K) indicator of the excitation gap at the filling factor fractional quantum Hall state in ultra-high quality AlGaAs/GaAs two…
