A Review on BGK Models for Gas Mixtures of Mono and Polyatomic Molecules
We consider the Bathnagar–Gross–Krook (BGK) model, an approximation of the Boltzmann equation, describing the time evolution of a single momoatomic rarefied gas and satisfying the same two main properties (conservation properties and entropy inequality).

Ultracold collisions of polyatomic molecules: CaOH
Ultracold collisions of the polyatomic species CaOH are considered, in internal states where the collisions should be dominated by long-range dipole–dipole interactions.

Boosting Charge Storage in Ferri/Ferrocyanide‐Based Alkaline Redox Flow Batteries
By modifying the solvation environment, cation engineering through Li+ substitution of traditional K+ or Na+ boosts the alkaline solubility of the ferri/ferrocyanide catholyte redox couple, providing a viable pathway to overcome the long‐standing challenge of energy density limitations for aqueous redox flow batteries (RBFs).

Measuring Fundamental Symmetry Violation in Polyatomic Molecules [PDF]
Open questions in fundamental physics, such as the cosmological origins of the observed imbalance of matter and antimatter, motivate the search for fundamental symmetry violating physics beyond the Standard Model (BSM).

Apart from (transition) metal (oxo)halides only few hosts stabilize chalcogenide cations in purely oxoanionic coordination environment. Herein, we report on five borosulfates containing the Se42+ ion and characterize the compounds using X‐ray diffraction, diffuse reflectance spectroscopy, density functional theory (DFT) calculations along with magnetic

Rotational Cooling of Trapped Polyatomic Molecules [PDF]
Controlling the internal degrees of freedom is a key challenge for applications of cold and ultracold molecules. Here, we demonstrate rotational-state cooling of trapped methyl fluoride molecules (CH3F) by optically pumping the population of 16 M-sublevels in the rotational states J=3,4,5, and 6 into a single level.

High-order harmonic generation by polyatomic molecules [PDF]
We present a theory of high-order harmonic generation by arbitrary polyatomic molecules based on the molecular strong-field approximation (MSFA) in the framework of the S-matrix theory.

Statistical-theory of multiphoton excitation of polyatomic-molecules based on the wigner function
This paper is aimed at establishing a statistical theory of rotational and vibrational excitation of polyatomic molecules by an intense IR laser. Starting from the Wigner function of quantum statistical mechanics, we treat the rotational motion in the ...

Rotational state detection of electrically trapped polyatomic molecules
Detecting the internal state of polar molecules is a substantial challenge when standard techniques such as resonance-enhanced multiphoton ionization or laser-induced fluorescense do not work.
