Nuclear conversion theory: molecular hydrogen in non-magnetic insulators [PDF]

Royal Society Open Science, 2016
The hydrogen conversion patterns on non-magnetic solids sensitively depend upon the degree of singlet/triplet mixing in the intermediates of the catalytic reaction. Three main ‘symmetry-breaking’ interactions are brought together.

Nonmagnetic Ground State in RuO_{2} Revealed by Muon Spin Rotation. [PDF]

Physical Review Letters
The magnetic ground state of single crystalline RuO_{2} was investigated by the muon spin rotation and relaxation (μSR) experiment. The spin precession signal due to the spontaneous internal magnetic field B_{loc}, which is expected in the magnetically ...

In-beam measurement of the hydrogen hyperfine splitting and prospects for antihydrogen spectroscopy

Nature Communications, 2017
Comparing the ground-state hyperfine structure of antihydrogen to that of hydrogen will provide insights into CPT symmetry in nature. Here the authors report the most precise in-beam measurement of this quantity for hydrogen to demonstrate the viability ...

Spectroscopic Measurement of Hydrogen Atom Density in a Plasma Produced with 28 GHz ECH in QUEST

Atoms, 2020
The spatial distribution of the hydrogen atom density was evaluated in a spherical tokamak (ST) plasma sustained only with 28 GHz electron cyclotron heating (ECH). The radially resolved Hδ emissivity was measured using multiple viewing chord spectroscopy

Anderson localization of a Rydberg electron

Physical Review Research, 2023
Highly excited Rydberg atoms inherit their level structure, symmetries, and scaling behavior from the hydrogen atom. We demonstrate that these fundamental properties enable a thermodynamic limit of a single Rydberg atom subjected to interactions with ...

Relativistic corrections for the ground electronic state of molecular hydrogen [PDF]

, 2017
A calculation of the ground-state energy of the hydrogen molecule with significantly improved numerical accuracy reveals an unexpected discrepancy between the energies predicted by the theory and those measured in experiments.

Numerical variational solution of hydrogen molecule and ions using one-dimensional hydrogen as basis functions

New Journal of Physics, 2020
The ground state solution of hydrogen molecule and ions are numerically obtained as an application of our scheme to solve many-electron multi-center potential Schrödinger equation by using one-dimensional hydrogen wavefunctions as basis functions.
