Researchers have prepared and manipulated subradiant states—in which collective effects slow down the decay of excited atoms—in a dense atomic cloud.

Building on a decade of advances in the understanding of neutron production and hot-spot physics, researchers at the National Ignition Facility are pursuing magnetized fusion fuel as a potentially disruptive way to boost the performance of laser-driven implosion.

Under the right conditions, self-propelled particles collectively transition from a state of liquid-gas coexistence to one where the particles can crystalize, according to simulations.

By injecting momentum into the fluid around an object, researchers can freely switch between obscuring the object’s presence and canceling hydrodynamic forces on it.

An experiment with a nanoscale clock verifies that a clock’s entropy per tick increases as the clock is made more precise.

The hard-to-explain masses of two coalescing black holes could be accounted for if they were the central black holes in two distant, tiny galaxies that merged.

According to the results of new neutron scattering experiments, polymer molecules in plastics move in ways that aren’t captured by commonly used models.

The latest dataset from gravitational-wave observatories has enough events to allow researchers to study properties of the whole population of black holes.
