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…
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…
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…
Observation of spontaneous valley polarization of itinerant electrons
Md. S. Hossain, M. K. Ma, K. A. Villegas Rosales +5
Memory or transistor devices based on electron's spin rather than its charge degree of freedom offer certain distinct advantages and comprise a cornerstone of spintronics. Recent y…
Observation of Spontaneous Ferromagnetism in a Two-Dimensional Electron System
Md. S. Hossain, M. K. Ma, K. A. Villegas Rosales +5
What are the ground states of an interacting, low-density electron system? In the absence of disorder, it has long been expected that as the electron density is lowered, the exchan…
