The pursuit of exotic phases of matter outside of the extreme conditions of a quantizing
magnetic field is a long-standing quest of solid state physics. Recent experiments have …

Quantum spin Hall (QSH) insulators are two-dimensional electronic materials that have a
bulk band gap similar to an ordinary insulator but have topologically protected pairs of edge …

The ability to control the underlying lattice geometry of a system may enable transitions
between emergent quantum ground states. We report in situ gate switching between …
