  • Ignition of a millimetre-sized pellet containing a mix of deuterium–tritium, published in 2022, puts to rest questions about the capability of lasers to ignite thermonuclear fuel.

    Year in Review
  • High-resolution images of the local charge distribution in materials often have a key role in establishing structure–property relationships. This Technical Review provides an overview of atomic-resolution charge density imaging techniques in transmission electron microscopy with a focus on recent advances in phase-retrieval methods and applications to heterogeneous materials.

    Technical Review
  • 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.

    Review Article
  • As physicists are increasingly reliant on artificial intelligence (AI) methods in their research, we ponder the role of human beings in future scientific discoveries. Will we be guides to AI, or be guided by it?

    Editorial
  • Magnetic resonance elastography captures multiscale mechanical information conveyed by shear waves, enabling noninvasive measurement of the physical behaviour of biological tissues—a behaviour that can change markedly with disease. This Review summarizes the basic technical concepts of magnetic resonance elastography and outlines preclinical and clinical applications.

    • Ingolf Sack
    Review Article
  • Even for flows as simple as those through pipes and channels, the nature of the transition to turbulence has remained elusive. This Perspective discusses how statistical mechanics and specifically directed percolation may provide an answer to this old problem.

    Perspective
  • For many complex or living systems, it is impossible to individually sample all their units, but subsampling can heavily bias the inference about their collective properties. This Perspective presents the subsampling problem and reviews recent developments to overcome this fundamental limitation.

    Perspective
  • “Girls don’t like physics” is a common refrain, but this perception has not always existed, nor does it occur everywhere in the world today. We call on our readers to fight such unfounded stereotypes.

    Editorial
  • The Dzyaloshinskii–Moriya interaction is an exchange coupling that appears in magnetic systems with spin–orbit coupling. This Technical Review systematically surveys first-principles-calculations methods for DMI in different material systems and for a range of induced magnetic phenomena.

    Technical Review
  • As artificial intelligence (AI) makes increasingly impressive contributions to science, scientists increasingly want to understand how AI reaches its conclusions. Matthew D. Schwartz discusses what it means to understand AI and whether such a goal is achievable — or even needed.

  • Non-Hermitian theory consists of mathematical structures that are used to describe open systems, which can give rise to non-Hermitian topology not found in Hermitian systems. This Review provides an overview of non-Hermitian band topology and discusses recent developments, such as the non-Hermitian skin effect and non-Hermitian topological classifications.

  • Venkatesh Narayanamurti and Jeffrey Y. Tsao discuss lessons learned from the success of the great 20th-century industrial research labs and warn against three common misconceptions about the nature and nurture of research.

  • This Expert Recommendation describes how high conversion efficiency in high-order harmonic generation can be achieved over a large range of pressures and medium lengths, following a hyperbolic equation, and provides design guidance for future high-flux extreme ultraviolet sources.
