AbstractThe microscopic mechanism of unconventional superconductivity in magic-angle twisted trilayer graphene is poorly understood. We show direct evidence for an in-plane magnetic order competing with the superconducting state motivated by theoretical proposals. We use two complementary electrical transport measurements.

AbstractThe relative twist angle between layers of near-lattice-matched van der Waals materials is critical for the emergent phenomena associated with moiré flat bands1,2,3. However, the concept of angle rotation control is not exclusive to moiré superlattices in which electrons directly experience a twist-angle-dependent periodic potential. Instead, it can also be used to induce programmable symmetry-breaking perturbations with the goal of stabilizing desired correlated states.

AbstractUnidirectional magnetoresistance (UMR) in a bilayer heterostructure, consisting of a spin-source material and a magnetic layer, refers to a change in the longitudinal resistance on the reversal of magnetization and originates from the interaction of non-equilibrium spin accumulation and magnetization at the interface.

AbstractSuperconducting (SC) states that break space-group symmetries of the underlying crystal can exhibit nontrivial spatial modulation of the order parameter. Previously, such states were intimately associated with the breaking of translational symmetry1,2, resulting in the density-wave orders3,4,5,6,7,8, with wavelengths spanning several unit cells9,10,11,12,13,14,15,16,17,18,19.

AbstractA fundamental requirement for quantum technologies is the ability to coherently control the interaction between electrons and photons. However, in many scenarios involving the interaction between light and matter, the exchange of linear or angular momentum between electrons and photons is not feasible, a condition known as the dipole approximation limit.

AbstractPoint defects in crystalline solids behave as optically addressable individual quantum systems when present in sufficiently low concentrations. In two-dimensional (2D) semiconductors, such quantum defects hold potential as versatile single photon sources.

DeviceThe device is based on a stack of two-dimensional materials as illustrated on Fig. 1a, which was assembled using the standard dry transfer technique28,29,30. It consists of a 35 nm thick top hBN layer, the Bernal BLG sheet, a 28 nm thick bottom hBN, and a graphite backgate layer. The BLG was subsequently contacted with 1D edge contacts28. Three metallic top gates (3 nm Cr, 20 nm Au) were evaporated on top of the stack to define two conducting channels.

AbstractVan der Waals heterostructures provide a versatile platform for tailoring electronic properties through the integration of two-dimensional materials. Among these combinations, the interaction between bilayer graphene and transition metal dichalcogenides (TMDs) stands out due to its potential for inducing spin–orbit coupling (SOC) in graphene.

AbstractOne of the most captivating properties of polaritons is their capacity to confine light at the nanoscale. This confinement is even more extreme in two-dimensional (2D) materials. 2D polaritons have been investigated by optical measurements using an external photodetector. However, their effective spectrally resolved electrical detection via far-field excitation remains unexplored.
