Cloud of virtual photons in the ground state of the hydrogen atom

Physical Review A, 1985
A spinless, nonrelativistic hydrogen atom coupled to an electromagnetic field is considered. The interaction is taken in the minimal-coupling form, and the ground state of the coupled system is obtained by straightforward perturbation theory. The form of the cloud of virtual photons surrounding the atom is studied through the quantum-mechanical average

Ground state of hydrogen as a zero-point-fluctuation-determined state

Physical Review D, 1987
We show here that, within the stochastic electrodynamic formulation and at the level of Bohr theory, the ground state of the hydrogen atom can be precisely defined as resulting from a dynamic equilibrium between radiation emitted due to acceleration of the electron in its ground-state orbit and radiation absorbed from zero-point fluctuations of the ...

Nonadiabatic energies of the ground state of the hydrogen molecule

Journal of Chemical Physics, 1995
Possible sources of residual errors in the theoretical energies of the hydrogen molecule are investigated. Nonadiabatic corrections are computed for all bound, J≤10 X 1Σg+ ro-vibrational states of the six isotopic hydrogen molecules. The new results improve significantly the overall agreement with accurate experimental transition frequencies.

Quadrupole moment in the ground state of atomic hydrogen

Journal of Physics B: Atomic and Molecular Physics, 1984
The quadrupole moment of the atomic hydrogen ground state is calculated. It arises due to a hyperfine interaction. Its true value is 20 times larger than the result obtained only taking into account the hyperfine mixing with the lowest d level.

Hyperfine Separation of Ground-State Atomic Hydrogen

Physical Review Letters, 1963
The hyperfine separation of hydrogen in its ground state was determined by means of the hydrogen maser. Two masers were operated simultaneously for purposes of tuning, checking internal consistency, and measuring the wall shift. A secondary frequency standard was also used. Corrections were made for the magnetic field offset, secondorder Doppler shift,

The Ground State of the Hydrogen Molecule

The Journal of Chemical Physics, 1933
The method used by Hylleraas in treating the He atom has been extended to the H2 molecule. The method consists of setting up a wave function as a series in the five variables required, electronic separation being introduced explicitly as one of the variables. The coefficients are then determined so as to produce the lowest energy.

Ground state of solid hydrogen at high pressures

Physical Review B, 1987
Quantum Monte Carlo calculations of the properties of bulk hydrogen at zero temperature have been performed. The only approximations involved in these calculations are the restriction to finite systems (64 to 432 atoms), the use of the fixed-node approximation to treat Fermi statistics, and the finite length of the Monte Carlo runs.
