Simulation of the hydrogen ground state in Stochastic Electrodynamics [PDF]

Physica Scripta, 2015
Stochastic electrodynamics is a classical theory which assumes that the physical vacuum consists of classical stochastic fields with average energy $\frac{1}{2}\hbar \omega$ in each mode, i.e., the zero-point Planck spectrum.

On the Stability of Classical Orbits of the Hydrogen Ground State in Stochastic Electrodynamics [PDF]

Entropy, 2016
De la Peña 1980 and Puthoff 1987 show that circular orbits in the hydrogen problem of Stochastic Electrodynamics connect to a stable situation, where the electron neither collapses onto the nucleus nor gets expelled from the atom.

Muonic hydrogen ground state hyperfine splitting [PDF]

Journal of Experimental and Theoretical Physics, 2003
Corrections of orders alpha^5, alpha^6 are calculated in the hyperfine splitting of the muonic hydrogen ground state. The nuclear structure effects are taken into account in the one- and two-loop Feynman amplitudes by means of the proton electromagnetic ...

Stochastic Electrodynamics: Renormalized Noise in the Hydrogen Ground-State Problem

Frontiers in Physics, 2020
The hydrogen ground-state problem is a touchstone for the theory of Stochastic Electrodynamics. Recently, we have shown numerically and theoretically that the H-atom self-ionizes after a characteristic time.

Ground-state charge transfer in single-molecule junctions covalent organic frameworks for boosting photocatalytic hydrogen evolution [PDF]

Nature Communications
Ground-state charge transfer plays a vital role in improving the photocatalytic performance of D-A type covalent organic frameworks. However, limited studies have explored the modulation of photocatalytic performance in COFs-based photocatalysts through ...

Unparticle contribution to the hydrogen atom ground state energy [PDF]

Physics Letters B, 2016
In the present work we study the effect of unparticle modified static potentials on the energy levels of the hydrogen atom. By using Rayleigh–Schrödinger perturbation theory, we obtain the energy shift of the ground state and compare it with experimental

Traces of Lorentz symmetry breaking in a Hydrogen atom at ground state [PDF]

European Physical Journal C, 2016
Some traces of a specific Lorentz symmetry breaking scenario in the ground state of the Hydrogen atom are investigated. It is used standard Rayleigh-Schr\"odinger perturbation theory in order to obtain the corrections to the the ground state energy and ...

Quadrupole arrangements and the ground state of solid hydrogen [PDF]

Physical Review B, 2020
The electric quadrupole-quadrupole ($\mathcal{E}_{qq}$) interaction is believed to play an important role in the broken symmetry transition from Phase I to II in solid hydrogen. To evaluate this, we study structures adopted by purely classical quadrupoles using Markov Chain Monte Carlo simulations of fcc and hcp quadrupolar lattices. Both undergo first-

Constraining Born–Infeld-like nonlinear electrodynamics using hydrogen’s ionization energy

European Physical Journal C: Particles and Fields, 2018
In this work, the hydrogen’s ionization energy was used to constrain the free parameter b of three Born–Infeld-like electrodynamics namely Born–Infeld itself, Logarithmic electrodynamics and Exponential electrodynamics.

Transport of ground-state hydrogen atoms in a plasma expansion [PDF]

Physical Review E, 2001
The transport of ground-state atomic hydrogen in the expansion of a thermal plasma generated from an Ar-H2 mixture is studied by means of laser-based diagnostic techniques. The flow of hydrogen atoms is investigated by two-photon excitation laser-induced fluorescence (LIF), whereas Ar atoms are probed by LIF as well as by UV Rayleigh scattering.
