Scaling and universality at dynamical quantum phase transitions

M Heyl - Physical Review Letters, 2015 - APS
Dynamical quantum phase transitions (DQPTs) at critical times appear as nonanalyticities
during nonequilibrium quantum real-time evolution. Although there is evidence for a close …

Dynamical phase diagram of quantum spin chains with long-range interactions

JC Halimeh, V Zauner-Stauber - Physical Review B, 2017 - APS
Using an infinite matrix product state (iMPS) technique based on the time-dependent

Detecting equilibrium and dynamical quantum phase transitions in Ising chains via out-of-time-ordered correlators

M Heyl, F Pollmann, B Dóra - Physical review letters, 2018 - APS
Out-of-time-ordered (OTO) correlators have developed into a central concept quantifying
quantum information transport, information scrambling, and quantum chaos. In this Letter …

Observation of dynamical quantum phase transitions with correspondence in an excited state phase diagram

T Tian, HX Yang, LY Qiu, HY Liang, YB Yang, Y Xu… - Physical Review Letters, 2020 - APS
