Unifying Finite-Temperature Dynamical and Excited-State Quantum Phase Transitions
Ángel L. Corps, Armando Relaño, Jad C. Halimeh
In recent years, various notions of dynamical phase transitions have emerged to describe far-from-equilibrium criticality. A unifying framework connecting these different concepts…
Mechanism of dynamical phase transitions: The complex-time survival amplitude
Ángel L. Corps, Pavel Stránský, Pavel Cejnar
Dynamical phase transitions are defined through non-analyticities of the survival probability of an out-of-equilibrium time-evolving state at certain critical times. They ensue fro…
Dynamical and excited-state quantum phase transitions in collective systems
Ángel L. Corps, Armando Relaño
We study dynamical phase transitions (DPTs) in quantum many-body systems with infinite-range interaction, and present a theory connecting the two kinds of known DPTs (sometimes ref…
Theory of dynamical phase transitions in quantum systems with symmetry-breaking eigenstates
Ángel L. Corps, Armando Relaño
We present a theory for the two kinds of dynamical quantum phase transitions, termed DPT-I and DPT-II, based on a minimal set of symmetry assumptions. In the special case of collec…
