Physics

Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts to both answer philosophical questions about the nature of the universe and provide solutions to technological problems.

    Experimentally following the ultrafast dynamics of microsolvated molecules is challenging due to the inherently produced soup mix of various gas-phase aggregates. Here, the authors exploit neutral-species selection to reveal intimate details of the UV-induced ultrafast dynamics in the prototypical indole-water system.

    Randomized measurements provide a feasible procedure for probing properties of many-body quantum states realized in today’s quantum simulators and quantum computers. This Review covers implementation, classical post-processing and theoretical performance guarantees of randomized measurement protocols, surveying their many applications and discussing current challenges.

    Quantum simulators allow for experimental studies of many-body systems in complex geometries, which has rarely been addressed by theory. Here the authors study many-body Hamiltonians on generic random graphs and show that many-body effects emerge only in a small class of exceptional, highly structured graphs.

    Tanner’s law describes the spreading dynamics of droplets made of Newtonian viscous fluids. Here, the authors demonstrate that this law remains valid for phase-separated binary liquids close to their critical point, and thus for all the associated universality class.

    Magnet-superconductor heterostructures provide a means to engineer unconventional spin-triplet Cooper pairs using ordinary superconductors. Here, a magnet-superconductor bilayer is predicted to host a composite quasiparticle consisting of spinful Cooper pairs coupled to a magnon excitation.

    Spin ices have magnetic moments arranged on a lattice with many possible ground-state configurations. Quantum effects can ‘melt’ the spin ice into a liquid that fails to form static order even at absolute zero despite strong interactions.

    A system of nine quantum bits has been used to simulate a state known as a holographic wormhole, a concept that features in attempts to reconcile quantum mechanics with the general theory of relativity.

    Manipulating the chirality of electron vortices using attosecond metrology allows the clocking of continuum–continuum transitions, bringing the dream of time-resolved quantum physics a little closer.
