Beyond the Flat-Band Paradigm: Open Orbits as a Route to Correlated States in Dispersive Moiré Minibands
Zihao Wang, Pablo M. Perez-Piskunow, Calvin Pei Yu Wong +16
The realization of fractional Chern insulators has largely relied on isolated flat bands in complex bilayer or multilayer moiré systems with ideal quantum geometry. Whether such ph…
Ferroelectric brightening of spin forbidden dark excitons in a WSe2/hybrid perovskite heterostructure
Xinyun Wang, Magdalena Grzeszczyk, Maxim Trushin +14
Long-lived dark excitons in monolayer WSe2 present promising candidates for carrying spin and valley information, but their optical access and spin manipulation have conventionally…
Valleytronics in 2D Materials Roadmap
Kyle L. Seyler, Giancarlo Soavi, Bent Weber +30
Valleytronics exploits non-equivalent energy extrema in the electronic band structure of crystalline solids -- the valley degree of freedom -- to encode, manipulate, and read out i…
Driving non-trivial quantum phases in conventional semiconductors with intense excitonic fields
Vivek Pareek, David R. Bacon, Xing Zhu +12
Inducing novel quantum phases and topologies in materials using intense light fields is a key objective of modern condensed matter physics, but nonetheless faces significant experi…
