October issue

This month we look at topological frequency combs, we review the physics of higher-order interactions in complex systems, and we consider the changing funding landscape of nuclear fusion.

    Nature Physics is taking part in Guided Open Access (OA), a pilot designed to make the process of publishing open access simpler, quicker, and more efficient. In Guided OA, an article is considered collaboratively at a group of associated journals, and authors are then guided through the process to find the best home for their work.

Nature Physics is a Transformative Journal; authors can publish using the traditional publishing route OR via immediate gold Open Access.

Our Open Access option complies with funder and institutional requirements.


  • Atoms in a semiconductor can have non-zero nuclear spins, creating a large ensemble with many quantum degrees of freedom. An electron spin coupled to the nuclei of a semiconductor quantum dot can witness the creation of entanglement within the ensemble.

  • Measurements of the phase diagram of water reveal first-order phase transitions to face- and body-centred cubic superionic ice phases. The former is suggested to be present in the interior of ice giant planets.

  • Quantum networks require a connection between quantum memories and optical links, which often operate in different frequency ranges. An optomechanical device exploiting the strain dependence of a colour-centre spin provides such a spin–optics interface at room temperature.

    • Molecular spin qubits that can be controlled electrically are typically susceptible to decoherence. Holmium molecular spins provide a solution by combining robust coherence with strong spin–electric coupling.

    • At high pressure and temperature, water forms two crystalline phases, known as hot ‘black’ ices due to their partial opaqueness. A detailed characterization of these phases may explain magnetic field formation in giant icy planets like Neptune.

    • Integrating quantum technology with existing telecom infrastructure is hampered by a mismatch in operating frequencies. An optomechanical resonator now offers a strain-mediated spin–photon interface for long-distance quantum networks.

European Strategy for Particle Physics

European Strategy for Particle Physics

The European Strategy for Particle Physics is the decision-making process underpinning the long-term future of particle physics in Europe. This Focus issue outlines the main proposals under consideration for the 2020 update to the strategy.
