Topological active matter

A Review discusses the properties of topological defects and topological band structures in active media, and an accompanying Comment describes the role of topolgical defects in biological matter.


  • Pervasive ML

    An ongoing series showcasing the breadth of machine learning applications in physics and trying to bring together different communities to share their problems and solutions.

  • On your wavelength

    On your wavelength is a new podcast about physics and publishing from the Nature journal editors. We talk to the authors and editors of recent papers discussing the latest insights.


    • The study of Bose–Einstein condensation in photonic systems has attracted strong interest in a variety of physical platforms, including conventional lasers and optical parametric oscillators, exciton and exciton–polariton gases, and photons in dye-filled cavities and propagating geometries. The focus of this Review is to highlight those universal phenomena that stem from the driven-dissipative, non-equilibrium nature of these systems and affect the static, dynamic, superfluid and coherence properties of the condensate.

    • Flat bands enhance the effect of electronic interactions and have emerged as a promising platform for superconductivity. This Review explains the quantum geometric origin of flat-band superconductivity and superfluidity, and discusses its relevance in graphene and ultracold gas moiré systems.

    • The polarization of the cosmic microwave background (CMB) may shed light on the nature of dark matter and dark energy, and on the origin of all structures in the Universe. Discovering a signature of such new physics in the CMB will require new observational and calibration strategies for future CMB experiments.

  • How did the leopard get its spots? According to Rudyard Kipling’s 1902 children’s story, the leopard’s spots were created by fingerprints of an Ethiopian man. Fifty years later, Alan Turing laid the mathematical foundations of our understanding of leopard spots today.

  • Machine learning is no longer restricted to data analysis and is now increasingly being used in theory, experiment and simulation, that is, all traditional aspects of research. Does this perhaps signal the dawn of a new paradigm?

  • An article in Physical Reviews X shows that quantum correlations can enhance the expressivity of generative models, suggesting new ways to develop improved (quantum-inspired) classical machine learning methods.
