Intervalley coherence and intrinsic spin–orbit coupling in rhombohedral trilayer graphene
Rhombohedral graphene multilayers provide a clean and highly reproducible platform to explore the emergence of superconductivity and magnetism in a strongly interacting electron system. Here we reveal a subtle...

Open AccessThe quantum geometric origin of capacitance in insulators
In band insulators, without a Fermi surface, adiabatic transport can exist due to the geometry of the ground state wavefunction. Here we show that for systems driven at a small but finite frequency ω, transport l...

Quantum-metric-induced nonlinear transport in a topological antiferromagnet
The Berry curvature and quantum metric are the imaginary part and real part, respectively, of the quantum geometric tensor, which characterizes the topology of quantum states1. The Berry curvature is known to gen...

Open AccessGeneral nonlinear Hall current in magnetic insulators beyond the quantum anomalous Hall effect
Can a generic magnetic insulator exhibit a Hall current? The quantum anomalous Hall effect (QAHE) is one example of an insulating bulk carrying a quantized Hall conductivity while insulators with zero Chern nu...

Open AccessPara-hydrodynamics from weak surface scattering in ultraclean thin flakes
Electron hydrodynamics typically emerges in electron fluids with a high electron–electron collision rate. However, new experiments with thin flakes of WTe2 have revealed that other momentum-conserving scattering ...

Half- and quarter-metals in rhombohedral trilayer graphene
Ferromagnetism is most common in transition metal compounds where electrons occupy highly localized d orbitals. However, ferromagnetic order may also arise in low-density two-dimensional electron systems1–5. Here...

Visualizing Poiseuille flow of hydrodynamic electrons
Hydrodynamics, which generally describes the flow of a fluid, is expected to hold even for fundamental particles such as electrons when inter-particle interactions dominate1. Although various aspects of electron ...

Open AccessSwitchable magnetic bulk photovoltaic effect in the two-dimensional magnet CrI3
The bulk photovoltaic effect (BPVE) rectifies light into the dc current in a single-phase material and attracts the interest to design high-efficiency solar cells beyond the pn junction paradigm. Because it is...
