Exploring Dynamical Quantum Phase Transitions via the Dynamical Phase Accumulated at an Equilibrium Critical Point
Han-Chuan Kou, Peng Li, Zhi-Han Zhang +1
We investigate dynamical quantum phase transitions (DQPTs) generated by a two-step linear quench with a finite waiting time at the equilibrium critical point. The waiting stage lea…
Interference of critical dynamics associated with zero modes
Zhi-Han Zhang, Han-Chuan Kou, Peng Li
We study the interference of critical dynamics associated with zero modes (ICDZM) in the generalized Creutz ladders using closed quench paths that pass through two critical points…
Optimized adiabatic-impulse protocol preserving Kibble-Zurek scaling with attenuated anti-Kibble-Zurek behavior
Han-Chuan Kou, Zhi-Han Zhang, Xin-Hui Wu +3
We propose an optimized adiabatic-impulse (OAI) protocol that substantially reduces the evolution time for crossing a quantum phase transition while preserving Kibble-Zurek (KZ) sc…
Critical dynamics and its interferometry in the one-dimensional p-wave-paired Aubry-André-Harper model
Zhi-Han Zhang, Han-Chuan Kou, Peng Li
In this work, we focus on the critical dynamics of the one-dimensional quasiperiodic p-wave-paired Aubry-André-Harper model, which exhibits a transition point between the gapped cr…
Kibble-Zurek scaling immune to anti-Kibble-Zurek behavior in driven open systems at the limit of loss difference
Han-Chuan Kou, Zhi-Han Zhang, Peng Li
We investigate the dissipative quench dynamics in a family of two-band fermionic systems by linearly ramping the staggered on-site energy. In the Lindblad formalism, we present an…
