Calculation of DC Stark Resonances for the Ammonia Molecule
Patrik Pirkola, Marko Horbatsch
A model potential previously developed for the ammonia molecule is treated in a single-center partial-wave approximation in analogy with a self-consistent field method developed by…
Non-monotonic dc Stark shifts in the rapidly ionizing orbitals of the water molecule
Patrik Pirkola, Marko Horbatsch
We extend a previously developed model for the Stark resonances of the water molecule. The method employs a partial-wave expansion of the single-particle orbitals using spherical h…
Partial-wave approach to the Stark resonance problem of the water molecule
Patrik Pirkola, Marko Horbatsch
A partial-wave method is developed to deal with small molecules dominated by a central atom as an extension of earlier single-center methods. In particular, a model potential for t…
Exterior Complex Scaling Approach for Atoms and Molecules in Strong DC Fields
Patrik Pirkola
We perform a short review of the history of quantum mechanics, with a focus on the historical problems with describing ionization theoretically in the context of quantum mechanics.…
Vanishing Absorption and Blueshifted Emission in FeLoBAL Quasars
Alireza Rafiee, Patrik Pirkola, Patrick B. Hall +3
We study the dramatic decrease in iron absorption strength in the iron low-ionization broad absorption line quasar SDSS J084133.15+200525.8. We report on the continued weakening of…
Demonstrating Martian Gravity
Patrik Pirkola, Patrick B. Hall
The surface gravity on Mars is smaller than the surface gravity on Earth, resulting in longer falling times. This effect can be simulated on Earth by taking advantage of air resist…
Multi-Epoch Observations of Extremely High-Velocity Emergent Broad Absorption
Jesse A. Rogerson, Patrick B. Hall, Paola Rodríguez Hidalgo +3
We present the discovery of the highest velocity CIV broad absorption line to date in the z=2.47 quasar SDSS J023011.28+005913.6, hereafter J0230. In comparing the public DR7 and D…
