RSS Nature Physics

Nature Physics offers news and reviews alongside top-quality research papers in a monthly publication, covering the entire spectrum of physics. Physics addresses the properties and interactions of matter and energy, and plays a key role in the development of a broad range of technologies. To reflect this, Nature Physics covers all areas of pure and applied physics research. The journal focuses on core physics disciplines, but is also open to a broad range of topics whose central theme falls within the bounds of physics.

  1. Emergence of fluctuating hydrodynamics in chaotic quantum systems
    Nature Physics, Published online: 12 August 2024; doi:10.1038/s41567-024-02611-z Fluctuating hydrodynamics posits that thermalization in non-equilibrium systems depends on equilibrium transport coefficients. This hypothesis is now tested by exploring the emergence of fluctuations in non-equilibrium dynamics of ultracold atoms.
  2. Nonlinear absorption of an X-ray pulse during the formation of warm dense matter
    Nature Physics, Published online: 08 August 2024; doi:10.1038/s41567-024-02594-x A bright, ultrashort X-ray pulse is used to transiently create and characterize warm dense copper. As the pulse intensity is increased, the opacity of copper is strongly altered. The recorded X-ray absorption spectra, substantiated by a theoretical electronic structure model, provide insight into the non-equilibrium electron dynamics during the formation of warm dense matter.
  3. Matter waves hang in there
    Nature Physics, Published online: 08 August 2024; doi:10.1038/s41567-024-02605-x An atom interferometer now maintains a spatial superposition state for 70 seconds, compared to few seconds in freely falling systems. This could improve measurements of the strength of gravitational fields and quantum gravity studies.
  4. New order in the copper oxide phase diagram
    Nature Physics, Published online: 02 August 2024; doi:10.1038/s41567-024-02602-0 A new ferroic-like phase has been discovered in highly doped superconducting cuprates. The existence of a well-defined order parameter on the supposedly disordered side of the phase diagram challenges the accepted theoretical framework.
  5. Spontaneous breaking of mirror symmetry in a cuprate beyond critical doping
    Nature Physics, Published online: 02 August 2024; doi:10.1038/s41567-024-02601-1 The Fermi liquid state in highly doped superconducting cuprates is normally thought of as disordered. Now, an observation of broken mirror symmetry in that phase suggests otherwise.
  6. Carrier density crossover and quasiparticle mass enhancement in a doped 5<i>d</i> Mott insulator
    Nature Physics, Published online: 02 August 2024; doi:10.1038/s41567-024-02564-3 The pseudogap in cuprates is often linked to superconductivity. Now bulk evidence for a pseudogap is found in doped non-superconducting Sr2IrO4, revealing that pseudogaps in doped Mott insulators are not necessarily a precursor to superconductivity.
  7. All real projective measurements can be self-tested
    Nature Physics, Published online: 01 August 2024; doi:10.1038/s41567-024-02584-z Quantum correlations are strong enough that classical users can verify that a device produces quantum entangled states using only the outcomes of local measurements. This self-testing approach has now been extended to verifying quantum measurements.
  8. Publisher Correction: Transverse emittance reduction in muon beams by ionization cooling
    Nature Physics, Published online: 30 July 2024; doi:10.1038/s41567-024-02616-8 Publisher Correction: Transverse emittance reduction in muon beams by ionization cooling
