Two studies find that fundamental quantum constraints rule out a previously proposed neutrino-laser scheme.

In this forward-looking PRL Essay, Peng Xue examines emerging non-Hermitian phenomena that challenge established paradigms in condensed matter and quantum physics, exploring the interface between non-...

Leggett made Nobel-prize-winning contributions to the theory of superfluidity in the 1970s

A coordinate transformation devised for an expanding universe leads to new insights into how a collapsing protogalaxy acquires a large magnetic field.

Gravitational waves emitted by the merger of two black holes have been detected, setting the course for a new era of observational astrophysics.

A combined experimental and theoretical study reveals the emergence of quantum chaos in a complex system, suggesting that it can be described with a universal theoretical framework.

A single-atom interferometer confirms Niels Bohr's resolution of a seemingly paradoxical thought experiment devised by Albert Einstein.

In an interview, the 2026 APS president outlines his career, his goals for the year, and where he finds optimism in challenging times.

We pay tribute to our friend and colleague, whose journalistic talent and commitment to inclusivity left an indelible mark on Physics Magazine.  

Analysis of a large dataset from the Tokyo Stock Exchange validates a universal power law relating the price of a traded stock to the traded volume.

A new approach stores and retrieves quantum states with record reliability, paving the way for improved quantum information processing.

Large-scale obstacles to crystal growth can throw the whole lattice off kilter, but quasicrystals can accommodate them without losing their atomic-scale order.  

We report the first observation of quantized energy levels for a macroscopic variable, namely the phase difference across a current-biased Josephson junction in its zero-voltage state. The position of...

A Bose-Einstein condensate of radioactive atoms could turn into a source of intense, coherent, and directional neutrino beams, according to a theoretical proposal.

Gravitational field equations describing binary black holes can be recast in a form resembling coupled Maxwell's equations for electrodynamics.

The final results from the Muon g − 2 experiment agree with the latest predictions of the muon’s magnetic properties—letting down hopes that the particle would upset the standard model’s applecart.

Models of how things spread often assume that transmission mechanisms are fixed over time. However, social contagions---the spread of ideas, beliefs, innovations---can lose or gain in momentum as they...

In this PRL Essay, Che Ting Chan offers a forward-looking overview of photonic crystals and how their design flexibility, symmetry properties, and experimental accessibility position them as powerful ...

Researchers have analyzed ``blank'' calibration images, seeking signs of dark matter moving through the telescope.

An experimental implementation of entanglement purification protocols with nonidentical input mixed states confirms the existence of residual entanglement in different error models.

In this new forward-looking PRL Essay, C\'esar de la Fuente and James J. Collins explore the ways in which machine learning and artificial intelligence can substantially accelerate the discovery of ne...

Failing to see any high-energy neutrinos allowed researchers to calculate an upper limit on the fraction of high-energy cosmic rays that are protons.
