Excited-state Quantum Phase Transitions in the Anharmonic Lipkin-Meshkov-Glick Model: Static Aspects
(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 ...

Excited-state Quantum Phase Transitions in the Anharmonic Lipkin-Meshkov-Glick Model: Dynamical Aspects
(American Physical Society, 2023)
The standard Lipkin-Meshkov-Glick (LMG) model undergoes a second-order ground-state quantum phase transition (QPT) and an excited-state quantum phase transition (ESQPT). The inclusion of an anharmonic term in the LMG ...

Digital quantum simulation of an extended Agassi model: Using machine learning to disentangle its phase-diagram
(American Physical Society, 2022)
A digital quantum simulation for the extended Agassi model is proposed using a quantum platform with eight trapped ions. The extended Agassi model is an analytically solvable model including both short range pairing and ...
