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…
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…
Equilibration time in many-body quantum systems
Talía L. M. Lezama, E. Jonathan Torres-Herrera, Francisco Pérez-Bernal +2
Isolated many-body quantum systems quenched far from equilibrium can eventually equilibrate, but it is not yet clear how long they take to do so. To answer this question, we use ex…
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…
Excited-state quantum phase transition and the quantum speed limit
Qian Wang, Francisco Perez-Bernal
We investigate the influence of an excited-state quantum phase transition (ESQPT) on the quantum speed limit (QSL) time of an open quantum system. The system consists of a central…
Identifying the order of a quantum phase transition by means of Wehrl entropy in phase-space
O. Castaños, M. Calixto, F. Pérez-Bernal +1
We propose a method to identify the order of a Quantum Phase Transition by using area measures of the ground state in phase space. We illustrate our proposal by analyzing the well…
