Origin of pinning disorder in magnetic-field-induced Wigner solids
Matthew L. Freeman, P. T. Madathil, L. N. Pfeiffer +5
At low Landau level filling factors (), Wigner solid phases of two-dimensional electron systems in GaAs are pinned by disorder, and exhibit a pinning mode, whose frequency is a…
Signatures of correlated defects in an ultra-clean Wigner crystal in the extreme quantum limit
P. T. Madathil, C. Wang, S. K. Singh +8
Low-disorder two-dimensional electron systems in the presence of a strong, perpendicular magnetic field terminate at very small Landau level filling factors in a Wigner crystal (WC…
Delocalization and Universality of the Fractional Quantum Hall Plateau-to-Plateau Transitions
P. T. Madathil, K. A. Villegas Rosales, C. T. Tai +5
Disorder and electron-electron interaction play essential roles in the physics of electron systems in condensed matter. In two-dimensional, quantum Hall systems, extensive studies…
Valley-tunable, even-denominator fractional quantum Hall state in the lowest Landau level of an anisotropic system
Md. Shafayat Hossain, M. K. Ma, Y. J. Chung +7
Fractional quantum Hall states (FQHSs) at even-denominator Landau level filling factors () are of prime interest as they are predicted to host exotic, topological states of matt…
Composite Fermion Mass
K. A. Villegas Rosales, P. T. Madathil, Y. J. Chung +4
Composite fermions (CFs), exotic quasi-particles formed by pairing an electron and an even number of magnetic flux quanta emerge at high magnetic fields in an interacting electron…
Understanding limits to mobility in ultra-high-mobility GaAs two-dimensional electron systems: The quest for 100 million cm/Vs and beyond
Yoon Jang Chung, A. Gupta, K. W. Baldwin +3
For several decades now, ultra-high-mobility GaAs two-dimensional electron systems (2DESs) have served as the hallmark platform for various branches of research in condensed matter…
