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.

Unparticle contribution to the hydrogen atom ground state energy
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

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 of metallic hydrogen [PDF]
Physical Review B, 1978 A proposed liquid state of metallic hydrogen at zero temperature is explored, and a variational upper bound to the ground-state energy is calculated. It is shown that the possibility that metallic hydrogen is a liquid around the metastable point (${r}_{s}=1.64$) cannot be ruled out.

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-

Quantum computing simulation of the hydrogen molecular ground-state energies with limited resources
Open Physics, 2021 In this article, the hydrogen molecular ground-state energies using our algorithm based on quantum variational principle are calculated. They are calculated through a simulator since the system of the present study (i.e., the hydrogen molecule) is ...

Measurement and Analysis of Atomic Relaxation Time in Active Hydrogen Atomic Clocks
Chinese Journal of Magnetic Resonance, 2022 The atomic relaxation time of a hydrogen atomic clock is the time required for atomic system after the selected state removing the atoms of the ground state hyperfine energy level (F = 0, mF = 0) and (F = 1, mF = −1) state to change from the (F = 1, mF =
