Single Phonon Detection for Dark Matter via Quantum Evaporation and Sensing of Helium
S. A. Lyon, Kyle Castoria, Ethan Kleinbaum +4
Dark matter is five times more abundant than ordinary visible matter in our Universe. While laboratory searches hunting for dark matter have traditionally focused on the electrowea…
Disorder broadening of even denominator fractional quantum Hall states in the presence of a short-range alloy potential
E. Kleinbaum, Hongxi Li, N. Deng +3
We study energy gaps of the and fractional quantum Hall states in a series of two-dimensional electron gases containing alloy disorder. We found that gaps at these…
Thermopower-based hot electron thermometry of helium surface states at 1.6 K
Ethan I. Kleinbaum, Stephen A. Lyon
We have developed a method to probe the temperature of surface state electrons (SSE) above a superfluid Helium-4 surface using the Seebeck effect. In contrast to previously used SS…
Finite Temperature Behavior in the Second Landau Level of the Two-dimensional Electron Gas
V. Shingla, E. Kleinbaum, A. Kumar +3
Reports of weak local minima in the magnetoresistance at , , , , , and in the second Landau level of the electron gas in GaAs/AlGaAs le…
Anomalous Gap Reversal of the and Fractional Quantum Hall States
Ethan Kleinbaum, Ashwani Kumar, L. N. Pfeiffer +2
In this work we report the opening of an energy gap at the filling factor , firmly establishing the ground state as a fractional quantum Hall state. This and other odd-den…
The Fractional Quantum Hall State in the Presence of Alloy Disorder
Nianpei Deng, G. C. Gardner, S. Mondal +3
We report quantitative measurements of the impact of alloy disorder on the fractional quantum Hall state. Alloy disorder is controlled by the aluminum content in the Al…
