Imaging flat band electron hydrodynamics in biased bilayer graphene
Canxun Zhang, Evgeny Redekop, Hari Stoyanov +12
Hydrodynamic electron transport arises when carrier kinetics are dominated by interelectron collisions rather than the relaxation of momentum out of the electron system. In recent…
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…
Imaging the Meissner effect and local superfluid stiffness in a graphene superconductor
Ruoxi Zhang, Benjamin A. Foutty, Owen Sheekey +15
We report the observation of the Meissner effect in a rhombohedral graphene superconductor, realized via direct imaging of the static fringe magnetic field. In our few-micron sampl…
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…
Evolution of charge correlations in the hole-doped kagome superconductor CsVTiSb
Ganesh Pokharel, Canxun Zhang, Evgeny Redekop +7
The interplay between superconductivity and charge correlations in the kagome metal CsVSb can be tuned by external perturbations such as doping or pressure. Here we present…
