    Laser cooling of rare-earth-doped silica may provide a route to vibration-free refrigeration of integrated photonic circuits and quantum sensors to reduce the thermal noise. Here, cooling of high-purity Yb-doped silica to 0.7 K below ambient temperature is demonstrated using sub-optimal laser parameters, and in spite of a substantial extra thermal load.

    Laser-driven ion acceleration is an important topic for next-generation compact accelerators and material characterisation. The authors present a theoretical study on ion acceleration with near-critical double-layer targets that supports the experimental realisation of these targets and the interpretation of experiments of laser-ion acceleration.

    Many features of a superconductor are encoded in the Josephson effect and understanding changes at the local level can help explain related phenomena. Here, the authors use scanning tunnelling microscopy to study local changes in the Josephson effect and how they relate to the transport channel configuration.

    The concept of arrow of time expressing time asymmetric nature is intrinsically related to the second law of thermodynamics and increase of entropy. The authors show how a thermodynamic bath expected to add to entropy increase can be the key to time reversal for an unknown quantum state, paving the way to universal algorithms sending temporal evolution of an arbitrary system backward in time.

    Curvature effects in a magnetic system are usually described by treating local and non-local interactions separately. Here, the authors develop a theory of curvilinear micromagnetism and report a non-local chiral interaction which is absent in flat systems.

    How friction in liquids emerges from conservative forces between atoms is currently not well-understood, but it is a crucial parameter for dynamic processes in liquid matter. Here, the authors combine frequency-resolved simulation data with theory to show that the friction felt by a single molecule occurs abruptly below a certain frequency.

    Yu–Shiba–Rusinov subgap excitations are associated with a range of interesting physics such as Majorana fermions, and so it is important to understand their intrinsic features. Here, the authors investigate the temperature dependence of the Yu–Shiba–Rusinov states in a hybrid nanowire–quantum dot system, demonstrating that the shift in energy does not follow the behaviour predicted by current models.

    While shock waves are widely used in clinical and biological research due to their ability to deform the cell’s membrane and its permeability, the mechanisms of such interaction are still unclear. Here, the authors propose a method that allows to monitor the dynamic deformation of a cell’s membrane in response to shock waves and its effect on permeability.

    Magnetism in the cuprates is crucial to understanding their superconducting properties and most studies focus on the antiferromagnetism related to Cu spins. Here, using polarised neutron diffraction the authors find evidence of a type of short range magnetic ordering in Ca-doped SrCuO spin-ladder compound whose origins may lie in magnetoelectric loop currents rather than Cu spins

    Intrinsic randomness, also known as spontaneous stochasticity, has been suggested to limit the finite-time predictability of multiscale chaotic dynamics, but an explicit demonstration of its effect is still lacking. Here, the authors use numerical simulations to show the existence of spontaneous stochasticity in the discontinuous shear layer leading to the Kelvin-Helmholtz instability.

Using weak and strong measurements in entangled photons, the authors show a correspondence between joint weak values and the inferred elements of reality in the polarization version of the EPR assertions.

    Entanglement is one of the most fascinating quantum properties, being a resource in quantum computation and an obstacle in classical simulations. The author analyses entanglement growth in terms of purity, and verifies the results by introducing a class of random Clifford circuits that conserve magnetization, finding that for systems with diffusive dynamics that entanglement growth differs depending on the dimension as well as between qubits or qutrits.

    Spin mediated unconventional superconductivity exhibits a sign changing order parameter which is often inferred from the observation of a spin resonance mode. Here, the authors demonstrate that the origin of the spin resonance mode for a heavy fermion superconductor may not lie, as previously thought, in the spin-excitonic bound state and therefore its relation to the ordering parameter needs to be reconsidered.

    While high harmonic x-ray sources are well established sources for ultrafast spectroscopy, the decrease in efficiency towards higher energies limits their application. Here, a loose-focused, TW mid-IR laser is used to generate high harmonic soft x-rays with pulse energies of a few nJ in the water window and easy energy scaling.

    In classical thermodynamics irreversibility occurs whenever a non-thermal system is brought into contact with a thermal environment. Using quantum trajectories the authors here establish two energetic footprints of quantum irreversible processes, and find that while quantum irreversibility leads to the occurrence of a quantum heat and a reduction of work production, the two are not linked in the same manner as the classical laws of thermodynamics would dictate.
