Interstitial-induced ferromagnetism in a two-dimensional Wigner crystal

Kyung-Su Kim, Chaitanya Murthy, Akshat Pandey +1

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

Exact Hole-induced Resonating-Valence-Bond Ground State in Certain $U = \infty$ Hubbard Models

Kyung-Su Kim

We prove that the motion of a single hole induces the nearest-neighbor resonating-valence-bond ground state in the $U = \infty$ Hubbard model on a triangular cactus - a tree-like var…
