  • Transparent conductive oxides are wide bandgap conductors that combine weak optical absorption. Here, the authors report a two-dimensional electronic state on the surface of La-BaSnO3 and study its properties using a combination of electronic structure measurements and DFT calculations.

  • The total reaction flux catalysed by immobilized enzymes depends on their spatial arrangement. The problem of optimizing the arrangement to maximize the reaction flux is analogous to a portfolio optimization problem, which is solved here to obtain the optimal strategy to position enzymes in a class of reaction-diffusion systems.

  • Multistability is the possibility of a dissipative quantum many-body system to have multiple steady states - it is intensely studied, but its existence remains controversial. The paper settles this by providing an exactly provable case, and also proves that boundary time crystals can exist in interacting lattice models, which was not known before.

  • Elucidating the different microscopic mechanisms approaching the glass transition is challenging, particularly when considering the evolution of a supercooled liquid. Here, using synchrotron-based methods, the authors report the evolution of the dynamics in supercooled metallic liquids and unpick the structural and kinetic contributions to the α-relaxation process near the glass transition.

  • In a bilayer semiconductor system, electron-hole excitations, of which the simplest are electron-hole pairs known as excitons, can form by the interaction of charge carriers across the layers to come in various guises depending on the number and type of the charge carriers involved. Here, the authors theoretically investigate the Wigner crystallization of charged interlayer excitons as a function of perpendicular magnetic field applied, discussing how this phase transition could be detected in photoluminescence experiments.

  • Quantum Random Number Generators (QRNG) are important components of cryptographic protocols including prepare-and-measure based quantum key distribution protocols. The authors demonstrate laboratory, as well as in-orbit operation of their QRNG, showing its use to implement a public randomness beacon.

  • Experiments indicate that the cuprates exhibit intertwined spin- and charge-stripe orders and have sizable electron-phonon interactions. Here, the authors use quantum Monte Carlo methods to investigate stripe orders in the Hubbard-Holstein model to shed light on the influence of electron-phonon coupling on static and fluctuating stripe order.

  • Low phase-noise THz wave generation is in high demand for applications such as wireless communications and radars. Here, the authors generate low-noise THz waves via photodetection of the carrier of a Kerr frequency comb, which is repetition-rate stabilized using a two-wavelength delayed self-heterodyne interferometer.

  • Positive lightning discharges are rare and not well understood. Here, the authors present observations from three positive discharges and demonstrate unexpected luminosity dips in the channel to ground, as well as transient coupling to a negative discharge nearby.
