Anisotropic Two-Dimensional Disordered Wigner Solid
Anisotropic Two-Dimensional Disordered Wigner Solid
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 anisotropic two-dimensional (2D) Wigner solid (WS), where electrons form an ordered array with an anisotropic lattice structure. Such a state has eluded experiments up to now …
