Recently, #nickelate La3Ni2O7 was found to be superconducting near 80K at high pressure. This work reports ARPES at ambient pressure, revealing flat bands with strong correlations that could be linked to #superconductivity. @NatureComms#CondensedMatter https://t.co/Kt5DwIeySX
Here the authors report a combined experimental and numerical study of the effect of interface roughness on variability of quantum dot spin qubits formed at the Si/SiO2 interface.

Here the authors put forward the concept of a high spin axion insulator with several peculiar properties, such as the absence of gapless surface states and tunability of the axion field by an external magnetic field. @NatureComms https://t.co/tb4Aj83JUi
The authors study universality on a non-homogeneous graph showing that its scaling theory is controlled by a single parameter, the spectral dimension. @NatureComms https://t.co/kWXApfANP3
Here the authors study the field-dependent electronic structure, in particular flat bands, of twisted monolayer-bilayer graphene, using nano-ARPES and explain its field-tunability and similarities to twisted bilayer and double-bilayer graphene.@NatureComms https://t.co/x08kLcqzqv
Here, using time-resolved error measurements, the authors link errors present in transmon qubits based on Nb electrodes to mechanical vibrations of a commonly used pulse tube cooler. @NatureComms https://t.co/0yqegNwvRo
The study of defects and boundaries in conformal field theory is challenging in dimensions higher than 2. The authors use the fuzzy sphere regularization approach to perform a non-perturbative analysis of defect conformal field theory in 3D. @NatureComms https://t.co/AB82maIkzd
Electron glass usually occurs in disordered insulating systems. This work reports glassy dynamics of conduction electrons in an electron-doped quantum paraelectric KTaO3, in the good metal regime. @NatureComms@Middey_Sri@iiscbangalore@Physics_at_IISc https://t.co/ekCmWD57sf

Photonic #timecrystal refers to a material whose dielectric properties oscillate in time. This theoretical work shows such behavior in the #excitonicinsulator candidate Ta2NiSe5 and explains enhanced THz reflectivity observed in experiments. @NatureComms

Here the authors demonstrate an electrostatically controlled Mott metal-insulator transition in a 2D metal-organic framework with a kagome structure. @BenjaminLowe96 @FLEETCentre @Monash_Science, @UQScience

Here the authors observe a planar thermal Hall effect in the Kitaev candidate material Na2Co2TeO6 and propose that it is generated by phonons. @NatureComms https://t.co/mn57rZP7ov
Using resonant inelastic x-ray scattering, the authors show that unconventional excitons in van der Waals antiferromagnet NiPS3 are primarily driven by Hund´s coupling and that they propagate similarly to two-magnon excitations.@BrookhavenLab@NatureComms https://t.co/9VkcjnDgTL
Ising machines are promising for solving NP-hard problems. Si et al. implement an Ising machine consisting of 80 superparamagnetic tunnel junctions with all-to-all connections and apply it to a large-scale traveling salesman problem.@NatureComms

The nature of the bulk insulating state in 1T-TaS2 is debated. Here the authors introduce a ladder-type structure with fractional misalignment of adjacent layers, showing that it becomes a Mott insulator due to decoupling between the layers.@NatureComms https://t.co/hSVQPm79R5
Condensation of bound states in continuum polariton modes has been demonstrated at low temperatures. Here the authors report the observation of such a state in a periodic air-hole perovskite-based photonic crystal at room temperature. @NatureComms https://t.co/oiGbDDdMOs
Here the authors use time-resolved pump-probe spectroscopy to demonstrate the effects of non-equilibrium correlations of moire excitons in WSe2/WS2 heterobilayers.@NatureComms
