  • The Kondo effect has been observed in a variety of systems, including carbon nanotube quantum dots and graphene in the presence of impurities. Here, the authors report the observation of the Kondo effect in bilayer graphene quantum dots and study its interplay with weak spin-orbit coupling.

  • A polariton is a hybrid excitation resulting from strong light–matter coupling. The magneto-transport measurements have now revealed the crucial role played by its electronic component.

  • The mechanisms behind the superconducting phase in magic-angle twisted bilayer graphene (MATBG) remain debated. Here, the authors investigate radio frequency-biased Josephson junctions in MATBG, providing insights into the electron-phonon coupling and superfluid stiffness of correlated electrons.

  • The interaction between proximal 2D materials can lead to fundamental changes in electronic properties. Here, the authors provide evidence of two distinct types of spin-orbit coupling induced in bilayer graphene through the presence of a proximal MoS2 layer.

  • A single electron quantum dot in bilayer graphene is a candidate for a spin-valley qubit, however its excited state spectrum has not been determined under relevant conditions. Here the authors accomplish this using time-resolved charge detection technique and set the new upper bound on the inter-valley mixing.

  • Gate-defined superconducting moiré devices offer high tunability for probing the nature of superconducting and correlated insulating states. Here, the authors report the Little–Parks and Aharonov–Bohm effects in a single gate-defined magic-angle twisted bilayer graphene device.

  • Using the valley degree of freedom in analogy to spin to encode qubits could be advantageous as many of the known decoherence mechanisms do not apply. Now long relaxation times are demonstrated for valley qubits in bilayer graphene quantum dots.

  • Sequencing initiatives have detected multiple types of mutations in cancer. Here the authors, analysing enhancer-targeting sequence data, show that small insertions in transcriptional enhancers are frequently found near oncogenes, and demonstrate how one mutation deregulates expression of LMO2 in leukemia cells.

  • Twisting bilayer graphene to specific angles can yield correlated phases. A superconducting quantum interference device made from this magic-angle twisted bilayer graphene makes it possible to control the phase drop across a Josephson junction in this material.

  • In situ electrostatic control of two-dimensional superconductivity is commonly limited due to large charge carrier densities. Now, by means of local gates, electrostatic gating can define a Josephson junction in a magic-angle twisted bilayer graphene device, a single-crystal material.

  • Isoprene oxidation products are deposited rapidly into poplar leaves, where they undergo detoxification, and up to 1.5% are reemitted to the atmosphere as methyl ethyl ketone, according to laboratory and field experiments and chemistry-transport model simulations.
