Quantum Signatures of Chaos in Anisotropic Quantum Rabi Model
Shangyun Wang, Songbai Chen, Jiliang Jing +2
Quantum chaos is an intriguing topic and has attracted a great deal of interests in quantum mechanics and black hole physics. Recently, the exponential growth of out-of-time-ordere…
Quantum instability and Ehrenfest time for an inverted harmonic oscillator
Shangyun Wang, Songbai Chen, Jiliang Jing
We investigate the classical-quantum correspondence in the inverted harmonic oscillator (IHO) system. It is shown that the out-of-time-order correlators (OTOCs) which the initial s…
Fluctuations in Extractable Work and Bounds on the Charging Power of Quantum Batteries
Shang-Yung Wang
Motivated by a recent disagreement about the claim that fluctuations in the free energy operator bound the charging power of a quantum battery, we present a critical analysis of th…
Comment on "Fluctuations in Extractable Work Bound the Charging Power of Quantum Batteries"
Shang-Yung Wang
In an article by García-Pintos et al. [Rev. Lett. 125, 040601 (2020)] the connection between the charging power of a quantum battery and the fluctuations of a "free energy operator…
Effect of system energy on quantum signatures of chaos in the two-photon Dicke model
Shangyun Wang, Songbai Chen, Jiliang Jing
We have studied entanglement entropy and Husimi distribution as a tool to explore chaos in the quantum two-photon Dicke model. With the increase of the energy of system, the li…
Informational work storage in quantum thermodynamics
Shang-Yung Wang
We present a critical examination of the difficulties with the quantum versions of a lifted weight that are widely used as work storage systems in quantum thermodynamics. To overco…
