Phenomenological characterization of the isomerization transition state of carbonyl sulfide
Amine Rafik, Jamil Khalouf-Rivera, F. Pérez-Bernal +2
Signatures of excited-state quantum phase transitions in the bending degree of freedom of triatomic systems that undergo an isomerization reaction have been recently evinced. In th…
Phase transitions, symmetries, and tunneling in Kerr parametric oscillators
Miguel A. Prado Reynoso, Edson M. Signor, Jamil Khalouf-Rivera +3
Quantum Kerr parametric oscillators (KPOs) are systems out of equilibrium with a wide range of applications in quantum computing, quantum sensing, and fundamental research. They ha…
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…
Calculation of Transition State Energies in the HCN-HNC Isomerization with an Algebraic Model
Jamil Khalouf-Rivera, Miguel Carvajal, Lea F. Santos +1
Recent works have shown that the spectroscopic access to highly-excited states provides enough information to characterize transition states in isomerization reactions. Here, we sh…
