Gravitational and Relativistic Deflection of X-Ray Superradiance
Wen-Te Liao, Sven Ahrens
Exploring Einstein's theories of relativity in quantum systems, for example by using atomic clocks at high speeds can deepen our knowledge in physics. However, many challenges stil…
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…
