Angular momentum conservation in two-atom superradiance
P. R. Berman, Zeyuan Wang, A. Kuzmich
Two-atom superradiance is studied for atoms having a J=0 ground state and a J=1 excited state. The atoms lie on the x-axis and are excited by a σ_{+}-polarized laser pulse propagat…

Field energy and angular momentum in spontaneous emission: A Schrödinger-picture approach
P. R. Berman, A. Kuzmich, P. W Milonni
A Schrödinger-picture approach is used to calculate the field energy and angular momentum radiated by an atom undergoing spontaneous emission. The calculation is carried out using…
