Physical Review A
PPPL applies quantum theory and Einstein's special relativity to plasma physics issues
Researchers at the US Department of Energy's Princeton Plasma Physics Laboratory have developed a theory of plasma waves that can infer these properties in greater detail than in standard approaches. The new research analyzes the plasma surrounding the pulsar by coupling Einstein's theory of relativity with quantum mechanics, which describes the motion of subatomic particles such as the atomic nuclei -- or ions -- and electrons in plasma.

Nuclear Fusion
PPPL physicist conducts experiments indicating efficiency of fusion start-up technique
Physicist Fatima Ebrahimi at the US Department of Energy's Princeton Plasma Physics Laboratory and Princeton University has for the first time performed computer simulations indicating the efficiency of a start-up technique for doughnut-shaped fusion machines known as tokamaks. The simulations show that the technique, known as coaxial helicity injection, could also benefit tokamaks that use superconducting magnets.

PPPL researchers advance understanding of turbulence that drains heat from fusion reactors
Physicists at the US Department of Energy's Princeton Plasma Physics Laboratory appear to have gained important new insights into what affects plasma turbulence, which can impact the leakage of heat from the fusion plasma within tokamaks. Understanding how fusion plasmas lose heat is crucial because the more a plasma is able to retain its heat the more efficient a fusion reactor can be.
