A Flow Equation Approach Striving Towards an Energy-Separating Hamiltonian Unitary Equivalent to the Dirac Hamiltonian with Coupling to Electromagnetic Fields
N. Schopohl, N. S. Cetin
The Dirac Hamiltonian for relativistic charged fermions minimally coupled to (possibly time-dependent) electromagnetic fields is transformed with a purpose-bui…
On the Theory of Light Propagation in Crystalline Dielectrics
Marius Dommermuth, Nils Schopohl
A synoptic view on the long-established theory of light propagation in crystalline dielectrics is presented, providing a new exact solution for the microscopic local electromagneti…
Observation of the motional Stark shift in low magnetic fields
Manuel Kaiser, Jens Grimmel, Lara Torralbo-Campo +5
We report on the observation of the motional Stark effect of highly excited Rb Rydberg atoms moving in the presence of a weak homogeneous magnetic field in a vapor cell. Emp…
On the spectrum, radial wave functions, and hyperfine splittings of the Rydberg states in heavy alkali atoms
Ali Sanayei, Nils Schopohl
We calculate the bound state spectrum of the highly excited valence electron in the heavy alkali atoms solving the radial Schrödinger eigenvalue problem numerically with an accurat…
Quasiclassical theory of quantum defect and spectrum of highly excited rubidium atoms
Ali Sanayei, Nils Schopohl, Jens Grimmel +3
We report on a significant discrepancy between recently published highly accurate variational calculations and precise measurements of the spectrum of Rydberg states in Rb o…
Geometric pi Josephson junction in d-wave superconducting thin films
A. Gumann, C. Iniotakis, N. Schopohl
A novel way to realize a pi Josephson junction is proposed, based on a weak link in an unconventional d-wave superconductor with appropriately chosen boundary geometry. The critica…
