Broadband Terahertz Time-domain Spectroscopy of Quantum Materials in a Dilution Refrigerator
Robert J. Vukelich, Tenzin Norden, Tracy G. Hastings +5
We have constructed a terahertz time domain spectroscopy system using a Bluefors dilution refrigerator with a 7 T split-coil magnet. Using a gallium arsenide single quantum well sa…
Shot-noise-driven macroscopic vibrations and displacement transduction in quantum tunnel junctions
Prasanta Kumbhakar, Anusha Shanmugam, Akhileshwar Mishra +4
Inherent randomness and the resulting stochastic behavior of fundamental particles manifested as quantum noise put a lower bound on measurement imprecision in the quantum measureme…
Particle-Hole Symmetry and the Fractional Quantum Hall Effect in the Lowest Landau Level
W. Pan, W. Kang, M. P. Lilly +5
We report on detailed experimental studies of a high-quality heterojunction insulated-gate field-effect transistor (HIGFET) to probe the particle-hole symmetry (PHS) of the FQHE st…
Bloch-Grüneisen nonlinearity of electron transport in GaAs/AlGaAs heterostructures
O. E. Raichev, A. T. Hatke, M. A. Zudov +1
We report on nonlinear transport measurements in a two-dimensional electron gas hosted in GaAs/AlGaAs heterostructures. Upon application of direct current, the low-temperature diff…
Detecting weak coupling in mesoscopic systems with a nonequilibrium Fano resonance
S. Xiao, Y. Yoon, Y. -H. Lee +5
A critical aspect of quantum mechanics is the nonlocal nature of the wavefunction, a characteristic that may yield unexpected coupling of nominally-isolated systems. The capacity t…
Terahertz magneto-optical spectroscopy of two-dimensional hole and electron systems
N. Kamaraju, W. Pan, U. Ekenberg +6
We have used terahertz (THz) magneto-optical spectroscopy to investigate the cyclotron resonance in high mobility two-dimensional electron and hole systems. Our experiments reveal…
Giant negative magnetoresistance in high-mobility 2D electron systems
A. T. Hatke, M. A. Zudov, J. L. Reno +2
We report on a giant negative magnetoresistance in very high mobility GaAs/AlGaAs heterostructures and quantum wells. The effect is the strongest at kG, where the magn…
Terahertz Coherent Control of a Landau-Quantized Two-Dimensional Electron Gas
T. Arikawa, X. Wang, D. J. Hilton +3
We demonstrate coherent control of cyclotron resonance (CR) in a two-dimensional electron gas (2DEG). We use a sequence of terahertz pulses to control the amplitude of CR oscillati…
Direct Measurement of Cyclotron Coherence Times of High-Mobility Two-Dimensional Electron Gases
X. Wang, D. J. Hilton, J. L. Reno +2
We have observed long-lived (~30 ps) coherent oscillations of charge carriers due to cyclotron resonance (CR) in high-mobility two-dimensional electrons in GaAs in perpendicular ma…
Coupling Remote States through the Continuum: Multi-State Fano Resonances
Y. Yoon, M. -G. Kang, T. Morimoto +6
We demonstrate a fully-tunable multi-state Fano system in which remotely-implemented quantum states interfere with each other through their coupling to a mutual continuum. On tunin…
