Exchange Interactions of a Wigner Crystal in a Magnetic Field and Berry Curvature: Multi-Particle Tunneling through Complex Trajectories

Kyung-Su Kim

We study how an out-of-plane magnetic field $B (r)$ and a Berry curvature $I^c ◯ (k)$ modify the exchange interactions in a two-dimensional Wigner crystal (WC) using a semi-…

Itinerant Ferromagnetism from One-Dimensional Mobility

Kyung-Su Kim, Veit Elser

We propose a universal kinetic mechanism for a half-metallic ferromagnet -- a metallic state with full spin polarization -- arising from strong on-site Coulomb repulsions between p…
