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 ...
