Fitting for the energy levels of hydrogen
David M. Jacobs, Marko Horbatsch
Atomic hydrogen energy levels calculated to high precision are required to assist experimental researchers working on spectroscopy in the pursuit of testing quantum electrodynamics…
Relativistic Ritz approach to hydrogen-like atoms II: spectral analysis of hydrogen and deuterium
David M. Jacobs
A long-distance effective theory of hydrogen-like atoms, dubbed the relativistic Ritz approach was recently introduced and some its theoretical consequences were explored. In this…
Relativistic Ritz approach to hydrogen-like atoms I: theoretical considerations
David M. Jacobs
The Rydberg formula along with the Ritz quantum defect ansatz has been a standard theoretical tool used in atomic physics since before the advent of quantum mechanics, yet this app…
Defect Theory of Positronium and Nontrivial QED Relations
David M. Jacobs
An effective theory of the excited states of positronium is derived and some of its consequences are explored. At large physical separation, the binding of the electron and positro…
Non-relativistic Effective Quantum Mechanics of the Coulomb Interaction
David M. Jacobs, Matthew Jankowski
We apply the ideas of effective field theory to nonrelativistic quantum mechanics. Utilizing an artificial boundary of ignorance as a calculational tool, we develop the effective t…
A perturbative method for resolving contact interactions in quantum mechanics
David M. Jacobs
Long-range effective methods are ubiquitous in physics and in quantum theory, in particular. Furthermore, the reliability of such methods is higher when the nature of short-ranged…
Robin boundary conditions are generic in quantum mechanics
Gwyneth Allwright, David M. Jacobs
Robin (or mixed) boundary conditions in quantum mechanics have received considerable attention in the last two decades, in particular, for applications to nanoscale systems. Howeve…
An artificial boundary approach for short-ranged interactions
David M. Jacobs
Real physical systems are only understood, experimentally or theoretically, to a finite resolution so in their analysis there is generally an ignorance of possible short-range phen…
Primordial constraints on inelastic macro dark matter revisited
David M. Jacobs, Gwyneth Allwright, Mpho Mafune +2
At present, the best model for the evolution of the cosmos requires that dark matter make up approximately of the energy content of the Universe. Most approaches to explain…
Resonant bar detector constraints on macro dark matter
David M. Jacobs, Glenn D. Starkman, Amanda Weltman
The current standard model of cosmology, CDM, requires dark matter to make up around of the total energy budget of the Universe. Yet, quite puzzlingly, there appears to b…
Macro Dark Matter
David M. Jacobs, Glenn D. Starkman, Bryan W. Lynn
Dark matter is a vital component of the current best model of our universe, CDM. There are leading candidates for what the dark matter could be (e.g. weakly-interacting massive…
Brane Stabilization and Regionality of Extra Dimensions
David M. Jacobs, Glenn D. Starkman, Andrew J. Tolley
Extra dimensions are a common feature of beyond the Standard Model physics. In a braneworld scenario, local physics on the brane can depend strongly on the brane's location within…
Brane Localization and Stabilization via Regional Physics
David M. Jacobs, Glenn D. Starkman, Andrew J. Tolley
Extra-dimensional scenarios have become widespread among particle and gravitational theories of physics to address several outstanding problems, including cosmic acceleration, the…
It's Hard to Learn How Gravity and Electromagnetism Couple
Yi-Zen Chu, David M. Jacobs, Yifung Ng +1
We construct the most general effective Lagrangian coupling gravity and electromagnetism up to mass dimension 6 by enumerating all possible non-minimal coupling terms respecting bo…
