Decoherence as a signature of an excited-state quantum phase transition
Relaño, Armando; Arias Carrasco, José Miguel; Dukelsky, Jorge; García Ramos, José Enrique; Pérez Fernández, Pedro (American Physical Society, 2008)We analyze the decoherence induced on a single qubit by the interaction with a two-level boson system with critical internal ...

Decoherence due to an excited-state quantum phase transition in a two-level boson model
Pérez Fernández, Pedro; Relaño, Armando; Arias Carrasco, José Miguel; Dukelsky, Jorge; García Ramos, José Enrique (American Physical Society, 2009)The decoherence induced on a single qubit by its interaction with the environment is studied. The environment is modeled ...

Quantum quench influenced by an excited-state phase transition
Pérez Fernández, Pedro; Cejnar, P.; Arias Carrasco, José Miguel; Dukelsky, Jorge; García Ramos, José Enrique; Relaño, Armando (American Physical Society, 2011)We analyze excited-state quantum phase transitions (ESQPTs) in three schematic (integrable and nonintegrable) models ...
