Excited-state quantum phase transitions in many-body systems with infinite-range interaction : localization, dynamics, and bifurcation

Santos, Lea F.; Távora, Marco; Pérez Bernal, Francisco (American Physical Society, 2016)

Excited state quantum phase transitions (ESQPTs) are generalizations of quantum phase transitions (QPTs) to excited levels. They are associated with local divergences in the density of states. Here, we investigate how the ...
Structure of eigenstates and quench dynamics at an excited state quantum phase transition

Santos, Lea F.; Pérez Bernal, Francisco (American Physical Society, 2015)

We study the structure of the eigenstates and the dynamics of a system that undergoes an excited state quantum phase transition (ESQPT). The analysis is performed for two-level pairing models characterized by a U(n + ...
