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 ...
