Wannier basis method for KAM effect in quantum mechanics
Chao Yin, Yu Chen, Biao Wu
The effect of Kolmogorov-Arnold-Moser (KAM) theorem in quantum systems is manifested in dividing eigenstates into regular and irregular states. We propose an effective method based…

Monopoles in non-Hermitian systems
Qi Zhang, Biao Wu
The monopole for the geometric curvature is studied for non-Hermitian systems. We find that the monopole contains not only the exceptional points but also branch cuts. As the mathe…

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…
