Landauer’s principle connects entropy and energy dissipation in non-equilibrium processes. An experiment now uses this principle to measure entropy production in a Bose gas to resolve contributions from correlations and dissipation.

Light at low power densities can be used to manipulate ferromagnetic domains in the two-dimensional van der Waals ferromagnet Fe₃GeTe₂. This capability could be used to engineer the behaviour of Fe₃GeTe₂-based devices.

Clock precision is thought to be fundamentally limited by entropy production in out-of-equilibrium systems. A theoretical work now introduces a quantum clock design where precision grows exponentially with dissipation.

Driven quantum systems can form long-lived states with emergent order, but their excitation properties remain largely unexplored. Now, an experiment shows that a driven superfluid exhibits sound modes characteristic of a one-dimensional supersolid.

The concept of resonant valence bond phases has inspired many areas of condensed matter physics, but few realistic models have been identified. Now an analytical solution of such a phase has been found for pyrochlore and related lattices.

One-dimensional critical fermionic models play an important role in many-body physics. Now it has been shown that any entangled state can be extracted from a bipartitioned critical fermion chain with an arbitrarily small change to the initial state.

Measurements play a crucial role in our daily lives; and we rely on metrology to ensure that measurements are accurate and comparable. Celebrating the 150th anniversary of the beginning of the global measurement system, we look into its future.

This month, we celebrate the 150-year anniversary of the signing of the Metre Convention and look to the future of metrology.

Many young metrologists have fascinating ideas that could shape the future of metrology. Chingis Kuanbayev and Kangyoung Sung tell us how the young professionals imagine what the field will look like beyond 2050.

Heliophysics focuses on understanding the different processes in the solar system and the influence of the Sun on space and planets. Collaboration between subfields of heliophysics and different communities needs to improve to advance the field.
