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…

Competition between fractional quantum Hall liquid and Wigner solid at small fillings: Role of layer thickness and Landau level mixing

K. A. Villegas Rosales, S. K. Singh, Meng K. Ma +6

What is the fate of the ground state of a two-dimensional electron system (2DES) at very low Landau level filling factors () where interaction reigns supreme? An ordered array o…

Ultra-high quality two-dimensional electron systems

Yoon Jang Chung, K. A. Villegas-Rosales, K. W. Baldwin +4

Two-dimensional electrons confined to GaAs quantum wells are hallmark platforms for probing electron-electron interaction. Many key observations have been made in these systems as…

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…
