Quantum dynamical speedup for correlated initial states被引量:1
《Communications in Theoretical Physics》2023年第7期95-102,共8页Alireza Gholizadeh Maryam Hadipour Soroush Haseli Saeed Haddadi Hazhir Dolatkhah 
The maximal evolution speed of any quantum system can be expressed by the quantum speed limit time.In this paper,we consider a model in which the system has a correlation with the environment.The influence of the init...

Zero Energy Anomaly in One-Dimensional Anderson Lattice with Exponentially Correlated Weak Diagonal Disorder
《Communications in Theoretical Physics》2012年第8期280-284,共5页王宗国 覃绍京 康凯 王垂林 
Supported by National Natural Science Foundation of China under Grant No.10374093;the Knowledge Innovation Project of Chinese Academy of Sciences
We calculated numerically the localization length of one-dimensional Anderson model with correlated diagonal disorder. For zero energy point in the weak disorder limit, we showed that the localization length changes c...

Superfluidity of Paired Bosons from Correlated Tunneling
《Communications in Theoretical Physics》2009年第10期611-614,共4页YANG Shi-Jie 
Supported by National Natural Science Foundation of China under Grant No.10874018;by the 973 Program Project under Grant No.2009CB929101
We study superfluidity of paired Bosonic atoms in optical lattices. The atoms have strong repulsive on-slte energy. Single atom tunneling is severely suppressed while the atom-pair may co-tunnel by the second order qu...
