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…
