Spin dynamics in relativistic light-matter interaction
Heiko Bauke, Sven Ahrens, Christoph H. Keitel +1
Various spin effects are expected to become observable in light-matter interaction at relativistic intensities. Relativistic quantum mechanics equipped with a suitable relativistic…
Electron-spin dynamics in elliptically polarized light waves
Heiko Bauke, Sven Ahrens, Rainer Grobe
We investigate the coupling of the spin angular momentum of light beams with elliptical polarization to the spin degree of freedom of free electrons. It is shown that this coupling…
Relativistic spin operators in various electromagnetic environments
Heiko Bauke, Sven Ahrens, Christoph H. Keitel +1
Different operators have been suggested in the literature to describe the electron's spin degree of freedom within the relativistic Dirac theory. We compare concrete predictions of…
Electron-spin dynamics induced by photon spins
Sven Ahrens, Heiko Bauke, Christoph H. Keitel +1
Strong rotating magnetic fields may cause a precession of the electron's spin around the rotation axis of the magnetic field. The superposition of two counterpropagating laser beam…
Comparison of mass renormalization schemes for simple model systems
E. V. Stefanovich, R. E. Wagner, Q. Su +1
We discuss an alternative method to mass renormalize a quantum field Hamiltonian based on a requirement that the vacuum and single-particle sectors are not self-scattering. We illu…
A study of local and non-local spatial densities in quantum field theory
R. E. Wagner, M. R. Ware, E. V. Stefanovich +2
We use a one-dimensional model system to compare the predictions of two different 'yardsticks' to compute the position of a particle from its quantum field theoretical state. Based…
