High-temperature simulation of the Raman spectra of the isotopologues CO and OCO
Eduardo Suárez, Christian Ostertag-Henning, Miguel Carvajal +1
Recently, experimental Raman spectra of the isotopologues CO and OCO at high temperature have been reported. Separately, a reliable approach…
Observations and chemical modeling of the isotopologues of formaldehyde and the cations of formyl and protonated formaldehyde in the hot molecular core G331.512-0.103
Edgar Mendoza, Miguel Carvajal, Manuel Merello +2
In the interstellar cold gas, the chemistry of formaldehyde (HCO) can be essential to explain the formation of complex organic molecules. On this matter, the massive and energe…
The Si+SO collision and an extended network of neutral-neutral reactions between silicon and sulphur bearing species
Danilo R. Campanha, Edgar Mendoza, Mateus X. Silva +4
The Si+SO reaction is investigated to verify its impact on the abundances of molecules with astrochemical interest, such as SiS, SiO, SO and others. According to our results Si…
Anharmonicity-induced excited-state quantum phase transition in the symmetric phase of the two-dimensional limit of the vibron model
Jamil Khalouf-Rivera, Francisco Pérez-Bernal, Miguel Carvajal
In most cases, excited state quantum phase transitions can be associated with the existence of critical points (local extrema or saddle points) in a system's classical limit energy…
Quantum fidelity susceptibility in excited state quantum phase transitions: application to the bending spectra of nonrigid molecules
J. Khalouf-Rivera, M. Carvajal, F. Pérez-Bernal
We characterize excited state quantum phase transitions in the two dimensional limit of the vibron model with the quantum fidelity susceptibility, comparing the obtained results wi…
Excited state quantum phase transitions in the bending spectra of molecules
Jamil Khalouf-Rivera, Francisco Pérez-Bernal, Miguel Carvajal
We present an extension of the Hamiltonian of the two dimensional limit of the vibron model encompassing all possible interactions up to four-body operators. We apply this Hamilton…
