How to generalize the Ehrenfest theorem and the uncertainty principle
Klaus Renziehausen, Ingo Barth
The Ehrenfest theorem and the Robertson uncertainty relation are well-known basic equations in quantum mechanics. However, there exist problematic cases, where the Ehrenfest theore…
The connection between Bohmian mechanics and many-particle quantum hydrodynamics
Klaus Renziehausen, Ingo Barth
Bohm developed the Bohmian mechanics (BM), in which the Schrödinger equation is transformed into two differential equations: A continuity equation and an equation of motion similar…
Ultrafast Preparation and Detection of Ring Currents in Single Atoms
Sebastian Eckart, Maksim Kunitski, Martin Richter +16
Quantum particles can penetrate potential barriers by tunneling (1). If that barrier is rotating, the tunneling process is modified (2,3). This is typical for electrons in atoms, m…
Many-particle quantum hydrodynamics: exact equations and pressure tensors
Klaus Renziehausen, Ingo Barth
In the first part of this paper, the many-particle quantum hydrodynamics (MPQHD) equations for a system containing many particles of different sorts are derived exactly from the ma…
Hole dynamics and spin currents after ionization in strong circularly polarized laser fields
Ingo Barth, Olga Smirnova
We apply the time-dependent analytical R-matrix theory to develop a movie of hole motion in a Kr atom upon ionization by strong circularly polarized field. We find rich hole dynami…
Nonadiabatic tunneling in circularly polarized laser fields. III. Comparison with experiment
Ingo Barth, Olga Smirnova
We compare results of the recent experiment by Herath et al [T. Herath, L. Yan, S. K. Lee, and W. Li, Phys. Rev. Lett. 109, 043004 (2012)] on strong-field nonadiabatic tunneling in…
