Unparticle contribution to the hydrogen atom ground state energy
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
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.

On the Stability of Classical Orbits of the Hydrogen Ground State in Stochastic Electrodynamics
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.

Quantum computing simulation of the hydrogen molecular ground-state energies with limited resources
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
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 =

On the ground state of the Dirac hydrogen atom under a minimal-length assumption
We point out an erroneous handling in the literature regarding corrections to the ground state energy of the Dirac hydrogen atom related to the presence of a minimal length.

Structure optimization for parameterized quantum circuits [PDF]
We propose an efficient method for simultaneously optimizing both the structure and parameter values of quantum circuits with only a small computational overhead. Shallow circuits that use structure optimization perform significantly better than circuits
