Fractional quantum Hall valley ferromagnetism in the extreme quantum limit
Md. Shafayat Hossain, M. K. Ma, Y. J. Chung +7
Electrons' multiple quantum degrees of freedom can lead to rich physics, including a competition between various exotic ground states, as well as novel applications such as spintro…
Robust Quantum Hall Ferromagnetism near a Gate-Tuned ν = 1 Landau Level Crossing
Meng K. Ma, Chengyu Wang, Y. J. Chung +5
In a low-disorder two-dimensional electron system, when two Landau levels of opposite spin or pseudospin cross at the Fermi level, the dominance of the exchange energy can lead to…
Even-Denominator Fractional Quantum Hall State at Filling Factor ν = 3/4
Chengyu Wang, A. Gupta, S. K Singh +6
Fractional quantum Hall states (FQHSs) exemplify exotic phases of low-disorder two-dimensional (2D) electron systems when electron-electron interaction dominates over the thermal a…
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…
Anisotropic, two-dimensional, disordered Wigner solid
Md. S. Hossain, M. K. Ma, K. A. Villegas-Rosales +5
The interplay between the Fermi sea anisotropy, electron-electron interaction, and localization phenomena can give rise to exotic many-body phases. An exciting example is an anisot…
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…
