A ruthenium oxide thermometer for dilution refrigerators operating down to 5 mK
S. A. Myers, H. Li, G. A. Csáthy
At the lowest temperatures achieved in dilution refrigerators, ruthenium oxide resistance thermometers often saturate and therefore lose their sensitivity. In an effort to extend t…
Observation of a transition from a topologically ordered to a spontaneously broken symmetry phase
N. Samkharadze, K. A. Schreiber, G. C. Gardner +3
Until the late 1980s, phases of matter were understood in terms of Landau's symmetry breaking theory. Following the discovery of the quantum Hall effect the introduction of a secon…
Observation of an anomalous density-dependent energy gap of the fractional quantum Hall state in the low density regime
N. Samkharadze, Dohyung Ro, L. N. Pfeiffer +2
We have studied the fractional quantum Hall state in a density-tunable sample at extremely low electron densities. For the densities accessed in our experiment, the Landau…
Exploration of the Limits to Mobility in Two-Dimensional Hole Systems in GaAs/AlGaAs Quantum Wells
J. D. Watson, S. Mondal, G. Gardner +2
We report on the growth and electrical characterization of a series of two-dimensional hole systems (2DHSs) used to study the density dependence of low temperature mobility in 20 n…
Quantitative Analysis of the Disorder Broadening and the Intrinsic Gap for the Fractional Quantum Hall State
N. Samkharadze, J. D. Watson, G. Gardner +4
We report a reliable method to estimate the disorder broadening parameter from the scaling of the gaps of the even and major odd denominator fractional quantum Hall states of the s…
