Spacetime algebra as a powerful tool for electromagnetism
Justin Dressel, Konstantin Y. Bliokh, Franco Nori
We present a comprehensive introduction to spacetime algebra that emphasizes its practicality and power as a tool for the study of electromagnetism. We carefully develop this natur…
Imaging the dynamics of free-electron Landau states
P. Schattschneider, Th. Schachinger, M. Stöger-Pollach +4
Landau levels and states of electrons in a magnetic field are fundamental quantum entities underlying the quantum-Hall and related effects in condensed matter physics. However, the…
Transverse spin and momentum in two-wave interference
Aleksandr Y. Bekshaev, Konstantin Y. Bliokh, Franco Nori
We analyze the interference field formed by two electromagnetic plane waves (with the same frequency but different wave vectors), and find that such field reveals a rich and highly…
Conservation of the spin and orbital angular momenta in electromagnetism
Konstantin Y. Bliokh, Justin Dressel, Franco Nori
We review and re-examine the description and separation of the spin and orbital angular momenta (AM) of an electromagnetic field in free space. While the spin and orbital AM of lig…
