Imaging the Shape of Electron Orbitals with Twisted X-rays

Ultrafast Science
Electron orbitals are quantum-mechanical wave functions that describe the spatial distribution of an electron, with the square of their magnitude representing the electron density. The concept of orbital forms foundation for visualizing and understanding

Quadruple Bonding of Alkaline Earth Atoms in AeCLi4 (Ae = Be − Ba) Complexes

Journal of Computational Chemistry, Volume 47, Issue 18, July 5, 2026.
Quantum chemical calculations of the complexes AeCLi4 (Ae = Be—Ba) show that the molecules have strong Ae‐Cli4 bonds, which consist of four dative bonds. The best signature of the chemical bonds is Ae CLi4. ABSTRACT The results of quantum chemical calculations of the complexes AeCLi4 (Ae = Be − Ba) are reported at the BP86‐D3(BJ)/def2‐QZVPP and CCSD(T)/

Ultracold long-range van der Waals Rydberg trimers

Communications Physics
Rydberg molecules are an essential ingredient of cold molecular sciences. Due to the richness of interactions between Rydberg atoms and neutral atoms, new kinds of Rydberg molecules and binding mechanisms are still to be discovered.

Multiscale quantum-defect theory and its application to atomic spectrum

New Journal of Physics, 2016
We present a multiscale quantum-defect theory based on the first analytic solution for a two-scale long range potential consisting of a Coulomb potential and a polarization potential.

Ab Initio Investigation of MgXe, Its Cation Mg+Xe and Clusters Mg+Xen: Electronic Structure, Spectroscopic Properties, and Temperature‐Dependent Absorption Spectra

International Journal of Quantum Chemistry, Volume 126, Issue 13, July 5, 2026.
Accurate potential energy curves, spectroscopic constants, and transition dipole moments were determined for the Mg+Xe and MgXe complexes. Spin–orbit effects were explicitly included for the Mg+Xe ionic system. Monte Carlo simulations were employed to investigate Mg+Xen clusters, and the temperature dependence of their absorption spectra was analyzed ...

Observation of the Stark effect in autoionising Rydberg states of molecular hydrogen

Chemical Physics Letters, 1991
Abstract The dc Stark effect is studied for autoionising Rydberg states of H 2 converging on the ν + =2 ionisation limit. The levels ( n = 13–22) are excited from the ground state using a coherent XUV source (bandwidth ≈ 1 cm −1 ) and are strongly perturbed by the field (15–2000 V/cm).

Long‐Range Interactions in Topological Superconducting Systems: A Mini Review

Advanced Physics Research, Volume 5, Issue 7, July 2026.
Long‐range interacting quantum systems are surveyed in this review, with an emphasis on the long‐range topological superconductor and its variants. Long‐range interactions decaying in a power‐law manner can lead to exotic phenomena that finds no analogue in short‐range regimes.

Strong-field photoelectron momentum imaging of OCS at finely resolved incident intensities

New Journal of Physics, 2019
Photoelectron momentum distributions from strong-field ionization of carbonyl sulfide with 800 nm central-wavelength laser pulses at various peak intensities from 4.6 to 13 × 10 ^13 W cm ^−2 were recorded and analyzed regarding resonant Rydberg states ...

Dynamical control in a prethermalized molecular ultracold plasma: Local dissipation drives global relaxation

Physical Review Research
Prethermalization occurs as an important phase in the dynamics of isolated many-body systems when coupled degrees of freedom relax in a subspace separated from a state of complete thermodynamic equilibrium by a gap in energy or other conserved quantity ...
