Van Hove Singularity-Driven Topological Magnetism in Twisted MoTe2
Heonjoon Park, Julian Stewart, Xiao-Wei Zhang +15
Van Hove singularities (vHSs) strongly amplify electron interactions and can stabilize correlated phases in topological bands. Here we report signatures of topological magnetism in…
Visualizing Electronic Structure of Twisted Bilayer MoTe2 in Devices
Cheng Chen, William Holtzmann, Xiao-Wei Zhang +12
The pursuit of emergent quantum phenomena lies at the forefront of modern condensed matter physics. A recent breakthrough in this arena is the discovery of the fractional quantum a…
Optical control over topological Chern number in moiré materials
Olivier Huber, Kilian Kuhlbrodt, Eric Anderson +7
Controlling quantum matter with light offers a promising route to dynamically tune its many-body properties, ranging from band topology to superconductivity. However, achieving suc…
Optical Control of Integer and Fractional Chern Insulators
William Holtzmann, Weijie Li, Eric Anderson +9
Optical control of topology, particularly in the presence of electron correlations, is a fascinating topic with broad scientific and technological impact. Twisted MoTe bilayer…
Universal Magnetic Phases in Twisted Bilayer MoTe
Weijie Li, Evgeny Redekop, Christiano Wang Beach +15
Twisted bilayer MoTe (tMoTe) has emerged as a robust platform for exploring correlated topological phases, notably supporting fractional Chern insulator (FCI) states at zer…
Observation of High-Temperature Dissipationless Fractional Chern Insulator
Heonjoon Park, Weijie Li, Chaowei Hu +13
The fractional quantum anomalous Hall effect has recently been experimentally observed in zero-field fractional Chern insulators (FCI). However, an outstanding challenge is the pre…
