  • For Chiara Salemi, a fourth-year physics graduate student in the group of Lindley Winslow, the Jerrold R. Zacharias Career Development Associate Professor of Physics, ABRACADABRA is the perfect instrument to work on during her PhD. "I wanted a small experiment so I could do all the different pieces of the experiment," Salemi says. (mit.edu)

  • With no interactions the four-component field ψ ( x ) should satisfy Dirac's free field equation (hence, natural units are employed with ħ and the speed of light c set equal to 1): where ℏ is the bare electron mass (i.e., before interactions are turned on),γ μ ,μ 0, 1, 2, 3 are 4 × 4 Dirac matrices, and the repeated index μ is summed over.
