The next generation of ultrahigh energy lasers will be able to produce extremely dense electron-positron plasmas and intense bursts of gamma rays, according to simulations, and both will lead to new types of experiments.
Macroscopic quantum properties of helium-, one of the simplest and oldest elements in the universe, continue to puzzle and amaze scientists. Supertransport in solid helium- is the most elusive and controversial conundrum of all.

In the Aharonov-Bohm effect, proposed in 1959, quantum particles are affected in measurable ways by the classical electromagnetic potential, previously regarded as a purely mathematical construct. The electromagnetic field is too far from the particles to have any direct influence.
