The need for accurate calculations on atoms and diatomic molecules is motivated by the
opportunities and challenges of such studies. The most commonly used approach for all …

The early 21st century is witnessing a breakthrough in the study of the thermal radiation of
neutron stars. Observations with modern space telescopes have provided a wealth of …

In high magnetic field calculations, anisotropic Gaussian type orbital (AGTO) basis functions
are capable of reconciling the competing demands of the spherically symmetric Coulombic …

For a wide range of magnetic fields, 0≤ B≤ 2000 au, we present a systematic comparative
study of the performance of different types of density-functional approximations in light atoms …

Although studies on the interaction of atoms and molecules with external magnetic fields are
more than 100 years old, beginning from the pre-quantum-mechanical days to the era of …

The helium atom in a strong magnetic field B⩽ 2.35× 10 5 T is studied with the help of the
Lagrange-mesh method, in the case of an infinitely heavy nucleus. An approximate …

Nonlinear dynamics in quantum theory is an old area which has received considerable
recent impetus. In particular, the possibility and detection of chaos in the quantum realm is a …

We have developed a new method for the fast computation of wavelengths and oscillator
strengths for medium-Z atoms and ions, up to iron, at neutron star magnetic field strengths …

The “released-phase” diffusion quantum Monte Carlo method is used to calculate the
ground-state energies of atoms with nuclear charges from Z= 2, 3, 4,…, 26 for magnetic field …

The fourth-rank hypermagnetizability tensor of a series of planar conjugated molecules—ie,
aromatic naphthalene, nonaromatic borazine, antiaromatic flattened cyclo-octatetraene …
