Researchers have applied physics theory and calculations to predict the presence of two new phenomena -- interspecies radiative transition (IRT) and the breakdown of the dipole selection rule -- in ...

Recent progress in kilojoule-scale high-intensity lasers has opened up new areas of research in radiography, laboratory astrophysics, high-energy-density physics, and fast-ignition (FI) laser fusion.

High energy density (HED) physics has critical applications in areas such as inertial confinement fusion and the stewardship of the nation’s nuclear weapons stockpile. Congress has requested that the ...

Physicists in the US have devised a new technique that brings us one step closer to the possibility of using magnetic nanowires as high-density data storage devices. The technique involves moving ...

Physicists have heated gold to over 19,000 Kelvin, more than 14 times its melting point, without melting it, smashing the long-standing “entropy catastrophe” limit. Using an ultra-fast laser pulse at ...

The units of density depend on the units used for mass and volume. The most commonly used units are grams per cubic centimetre (g/cm³) or kilograms per cubic metre (kg/m³). These balloons are the same ...

Mercury’s high density and large iron content could have been caused by magnetically excited collisions within part of the Sun’s protoplanetary disc, suggests new research from scientists at the ...

The National Science Foundation (NSF) has announced funding for a new Physics Frontier Center, hosted at the University of Rochester, with Princeton co-principal investigators Adam Burrows, professor ...
