Two-dimensional semiconductors, such as transition metal dichalcogenides, have
demonstrated tremendous promise for the development of highly tunable quantum devices …

Wigner predicted that when the Coulomb interactions between electrons become much
stronger than their kinetic energy, electrons crystallize into a closely packed lattice. A variety …

Electrons in topological flat bands can form new topological states driven by correlation
effects. The pentalayer rhombohedral graphene/hexagonal boron nitride (hBN) moiré …

We propose a minimal “three-patch model” for the anomalous Hall crystal (AHC), a
topological electronic state that spontaneously breaks both time-reversal symmetry and …

Two recent electronic transport experiments from Columbia University and Harvard
University have reported record high mobility and low channel densities in flux-grown …

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 …

Quantum devices such as spin qubits have been extensively investigated in electrostatically
confined quantum dots using high-quality semiconductor heterostructures like GaAs and Si …

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) …

The two-dimensional electron gas (2DEG) is a fundamental model, which is drawing
increasing interest because of recent advances in experimental and theoretical studies of …

The two-dimensional Wigner crystal (WC) occurs in the strongly interacting regime (rs≫ 1) of
the two-dimensional electron gas (2DEG). The magnetism of a pure WC is determined by …
