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 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…
Bloch Ferromagnetism of Composite Fermions
Md. Shafayat Hossain, Tongzhou Zhao, Songyang Pu +9
In 1929 Felix Bloch suggested that the paramagnetic Fermi sea of electrons should make a spontaneous transition to a fully-magnetized state at very low densities, because the excha…
Precise Experimental Test of the Luttinger Theorem and Particle-Hole Symmetry for a Strongly Correlated Fermionic System
Md. S. Hossain, M. A. Mueed, M. K. Ma +6
A fundamental concept in physics is the Fermi surface, the constant-energy surface in momentum space encompassing all the occupied quantum states at absolute zero temperature. In 1…
Spin Reversal of a Quantum Hall Ferromagnet at a Landau Level Crossing
M. Lupatini, P. Knüppel, S. Faelt +4
When Landau levels (LLs) become degenerate near the Fermi energy in the quantum Hall regime, interaction effects can drastically modify the electronic ground state. We study the qu…
Geometric Resonance of Four-Flux Composite Fermions
Md. Shafayat Hossain, Meng K. Ma, M. A. Mueed +6
Two-dimensional interacting electrons exposed to strong perpendicular magnetic fields generate emergent, exotic quasiparticles phenomenologically distinct from electrons. Specifica…
