Super-exponential scrambling of Out-of-time-ordered correlators
Wen-Lei Zhao, Yue Hu, Zhi Li +1
Out-of-time-ordered correlators (OTOCs) are an effective tool in characterizing black hole chaos, many-body thermalization and quantum dynamics instability. Previous research findi…

Signatures of excited state quantum phase transitions in quantum many body systems: Phase space analysis
Qian Wang, Francisco Pérez-Bernal
Using the Husimi function, we investigate the phase space signatures of the excited state quantum phase transitions (ESQPTs) in the Lipkin and coupled top models. We show that the…

Performance of quantum heat engines under the influence of long-range interactions
Qian Wang
We examine a quantum heat engine with an interacting many-body working medium consisting of the long-range Kitaev chain to explore the role of long-range interactions in the perfor…
