All-to-All interactions via multifractal wavefunction geometry
YouYoung Joung, Jemin Park, SungBin Lee
We uncover a generic mechanism through which the intrinsic geometry of multifractal quantum wavefunctions generates effective all-to-all interactions in many-body systems. By analy…

Entanglement switching via mobility edges in a quasiperiodic chain
YouYoung Joung, Junmo Jeon, SungBin Lee
We propose quasiperiodic chains with tunable mobility edge physics, as a promising platform for engineering long-range quantum entanglement. Using the generalized Aubry-André mode…
