Microscope for Quantum Dynamics with Planck Cell Resolution
Zhenduo Wang, Jiajin Feng, Biao Wu
We introduce the out-of-time-correlation(OTOC) with the Planck cell resolution. The dependence of this OTOC on the initial state makes it function like a microscope, allowing us to…

Genuine Quantum Chaos and Physical Distance Between Quantum States
Zhenduo Wang, Yijie Wang, Biao Wu
We show that there is genuine quantum chaos despite that quantum dynamics is linear. This is revealed by introducing a physical distance between two quantum states. Qualitatively d…

Generalized Wigner-von Neumann entropy and its typicality
Zhigang Hu, Zhenduo Wang, Biao Wu
We propose a generalization of the quantum entropy introduced by Wigner and von Neumann in 1929 [Zeitschrift für Physik 57, 30 (1929)]. Our generalization is applicable to both qua…
