Anharmonicity-induced excited-state quantum phase transition in the symmetric phase of the two-dimensional limit of the vibron model

Khalouf-Rivera, Jamil; Pérez Bernal, Francisco; Carvajal Zaera, Miguel (2022)

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 functional. However, an excited-state ...
Estudio de las transiciones de fase cuánticas de estado fundamental y de estados excitados en el límite bidimensional del modelo de vibrones: aplicación al espectro de flexión molecular

Khalouf-Rivera, Jamil (Universidad de Huelva, 2022)

El estudio de la estructura molecular es muy relevante en diferentes campos de la física. En particular, se emplean métodos clásicos, semiclásicos y cuánticos para la descripción de la estructura molecular. En la presente ...
Excited state quantum phase transitions in the bending spectra of molecules

Khalouf-Rivera, Jamil; Pérez Bernal, Francisco; Carvajal Zaera, Miguel (Elsevier, 2021)
Excited-state quantum phase transitions in the anharmonic Lipkin-Meshkov-Glick model: Static aspects

Gamito, J.; Khalouf-Rivera, Jamil; Arias Carrasco, José Miguel; Pérez Fernández, Pedro; Pérez Bernal, Francisco (American Physical Society, 2022)

The basic Lipkin-Meshkov-Glick model displays a second-order ground-state quantum phase transition and an excited-state quantum phase transition (ESQPT). The inclusion of an anharmonic term in the Hamiltonian implies a ...
Quantum fidelity susceptibility in excited state quantum phase transitions: Application to the bending spectra of nonrigid molecules

Khalouf-Rivera, Jamil; Carvajal Zaera, Miguel; Pérez Bernal, Francisco (SciPost Foundation, 2022-01-04)

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 with the information provided by the ...
