We consider the mechanism of formation of isolated localized wave structures in the diatomic Fermi-Pasta-Ulam (FPU) model. Using a singular multiscale asymptotic analysis in the limit of high mass mismatch between the alternating elements, we obtain the typical slow-fast time scale separation and formulate the Fredholm orthogonality condition approximating a sequence of mass ratios supporting t...

Confinement effects of Aharonov-Bohm (AB) flux and magnetic fields with topological defect on CO diatomic molecule modeled by screened modified Kratzer potential is investigated in this paper. The all-encompassing the result a strongly repulsive system. We discover that collective effect intense than lone dual consequently there substantial shift bound state energy also find to sustain low-ener...

We investigate the classical and quantum mechanics of diatomic molecules in noncollinear (tilted) static electric and nonresonant linearly polarized laser fields. The classical diatomic in tilted fields is a nonintegrable system, and we study the phase space structure for physically relevant parameter regimes for the molecule KCl. While exhibiting low-energy (pendular) and high-energy (free-rot...

The advancement in the acquisition of spectral data from meteors, as well capability to analyze meteoritic entries ground testing facilities, requires assessment performance software tools for simulation spectra different species. Plasma Radiation Database, PARADE, is a line-by-line emission calculation tool. This article presents extensions implemented meteor with additional atomic species Na,...

Coupled cluster CCSD(T) calculations using the aug-cc-pVQZ basis set were performed on structures and energies of complexes O3-HF, O3-HCl, O3-OH, O3-H2, O3-N2, O3-CO, O3-O2, O3-F2, O3-Cl2, O3-ClF. Most have Cs symmetry, with symmetry plane being ozone (for hydrogen bonded O3-HF to O3-OH for halogen O3-Cl2 O3-ClF) or perpendicular most others). Dissociation De range from 718 1137 cm−1 O3-HCl com...
