Phys.org / Two paths, one flux: Trapped ions simulate Aharonov–Bohm interference in a lattice gauge theory
In a new Nature Physics study, researchers demonstrated the Aharonov-Bohm effect in a quantum simulation of a lattice gauge theory using a hybrid trapped-ion quantum computer.
Phys.org / Breaking the ice: Scientists use attracting particles to form an anti-spin ice
In a recent Nature Communications study, researchers have reported the realization of an anti-spin ice, a system that does the opposite of conventional spin ices by breaking the ice rule that governs them.
Phys.org / Measuring regrowth: Erk gradients guide zebrafish fins back to their original size after injury
In a new Nature Physics study, researchers found that fin regrowth in zebrafish is driven by a brief burst of growth signal at the fin tip, sized to the amount lost, which sets up gradients of Erk activity that guide the ...
Phys.org / Bending nanoribbons tunes diamond's light emission without doping
In a new Physical Review Letters study, researchers have demonstrated that bending diamond nanostructures can tune the light they emit without doping.
Phys.org / Magnetic order survives weak quantum fluctuations in gapless magnets
In a new study published in Physical Review Letters, researchers have shown that magnetic order can survive weak quantum fluctuations in disordered magnets that lack an energy gap. The work establishes robust ferromagnetism ...
Phys.org / Particle shape and size predict asteroid strength, revealing Bennu's surface is 50 times weaker than ground coffee
In a new Nature Communications study, researchers developed a universal scaling framework for the strength of granular asteroids, showing that their tensile strength can be predicted from the size and shape of their constituent ...
Phys.org / 'Flying focus' laser overcomes key limitation in plasma-based particle accelerators
In a new Nature Physics study, researchers accelerated electrons to more than twice the energy predicted by the traditional dephasing limit for laser-plasma accelerators operating over the same distance. This was made possible ...
Phys.org / Physicists link the Riemann Hypothesis to phase transitions in quantum systems
A new study in Nature Communications has established a link between the Riemann Hypothesis and dynamical phase transitions in engineered quantum systems, demonstrating the effect on a quantum processor.
Phys.org / Physicists capture first direct evidence of a Floquet topological state
A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a novel light-induced phase of matter that, until now, has existed only on paper and in simulations. Topological ...
Phys.org / Physicists demonstrate Hong–Ou–Mandel interference with more than 10 atoms
In a new study published in Nature Physics, researchers have demonstrated the Hong–Ou–Mandel (HOM) effect with up to 12 indistinguishable neutral atoms—an effect that has been predominantly observed in photonic systems.
Phys.org / Scientists find molecular-level evidence for two structures in liquid water
A study published in Nature Physics provides new molecular-level evidence from simulations that liquid water is not a single uniform substance, but a constantly shifting mixture of two distinct microscopic structures.
Phys.org / Warming unlocks ancient carbon in Tibetan permafrost, triggering climate tipping point
A new study in Nature Communications finds a critical climate tipping point in Tibetan permafrost ecosystems. Warming of 2–4 degrees Celsius triggers a self-reinforcing cycle of carbon release that could significantly accelerate ...
Phys.org / IceCube detects break in cosmic neutrino spectrum, ruling out simple power-law model
A new study published in Physical Review Letters by the IceCube Collaboration reports evidence that the energy spectrum of astrophysical neutrinos is not a simple straight line.
Phys.org / Hydrogen puts quantum wormhole conjecture to the test
A new Physical Review Letters study places constraints on the ER = EPR conjecture, showing that under the authors' assumptions, the conjecture would imply possible alterations to the hyperfine structure and effective charge ...
Phys.org / Universal quantum protocol extracts maximum work without knowing a system's state in advance
A new study published in Nature Communications has shown that in the asymptotic limit, extracting the maximum possible work from many copies of a quantum system does not require knowing exactly what state that system is in.
