von Neumann entropy and localization properties of two interacting particles in one-dimensional nonuniform systems
Longyan Gong, Peiqing Tong
With the help of von Neumann entropy, we study numerically the localization properties of two interacting particles (TIP) with on-site interactions in one-dimensional disordered, q…

Von Neumann entropy and localization-delocalization transition of electron states in quantum small-world networks
Longyan Gong, Peiqing Tong
The von Neumann entropy for an electron in periodic, disorder and quasiperiodic quantum small-world networks(QSWNs) are studied numerically. For the disorder QSWNs, the derivative…
