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.

First, let’s look at gravity. On the surface of the Earth, the usual model for gravitational force is the object’s mass times the gravitational field (represented by g) where g is about 9.8 Newtons ...

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 ...

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 ...

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 ...

Figure 1: PIC simulation and spectra from plasma generated by femtosecond pulse irradiation of a vertically aligned array of 55-nm-diameter Ni nanowires. Figure 2: Single-shot M-shell spectra of ...

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 ...

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 ...
