New Journal of Physics, 2020 Abstract Is there any entanglement in the simplest ubiquitous bound system? We study the solutions to the time-independent Schrödinger equation for a hydrogenic system and devise two entanglement tests for free and localised states. For free hydrogenic systems, we compute the Schmidt basis diagonalisation for general energy eigenstates ...

The impact of hydrogen on the ductility loss of bainitic Fe–C alloys [PDF]
, 2016 The influence of hydrogen on the mechanical properties of generic lab-cast Fe-C bainitic alloys is studied by tensile tests on notched samples. The bainitic microstructure is induced in a 0.2% C and 0.4% C Fe-C alloy by an appropriate heat treatment. The

Technical and Economic Viability of Underground Hydrogen Storage
Hydrogen, 2023 Considering the mismatch between the renewable source availability and energy demand, energy storage is increasingly vital for achieving a net-zero future. The daily/seasonal disparities produce a surplus of energy at specific moments.

Hydrogen microstructure in hydrogenated amorphous silicon [PDF]
Physical Review B, 1996 We present a method to determine the local hydrogen bonding structure in hydrogenated amorphous silicon from infrared spectroscopy measurements. This approach is based on a different oscillator strength and refractive index for hydrogen atoms located in the isolated and clustered phase.

Ionization of Hydrogen and Hydrogenic Ions by Antiprotons [PDF]
Physical Review Letters, 1996 Presented here is a description of the ionization of hydrogen and hydrogenic ions by antiproton-impact, based on very large scale numerical solutions of the time-dependent Schr dinger equation in three spatial dimensions and on analysis of the topology of the electronic eigenenergy surfaces in the plane of complex internuclear distance.
