An optimized infinite time-evolving block decimation algorithm for lattice systems
《Chinese Physics B》2023年第4期171-174,共4页许军军 
Project supported by Fundamental Research Funds for the Central Universities(Grant No.FRF-TP-19-013A3)。
The infinite time-evolving block decimation algorithm(i TEBD)provides an efficient way to determine the ground state and dynamics of the quantum lattice systems in the thermodynamic limit.In this paper we suggest an o...

Dynamical signatures of the one-dimensional deconfined quantum critical point
《Chinese Physics B》2022年第5期73-82,共10页Ning Xi Rong Yu 
Project supported by the National Science Foundation of China(Grant No.12174441);the Fundamental Research Funds for the Central Universities,China;the Research Funds of Remnin University of China(Grant No.18XNLG24)。
We study the critical scaling and dynamical signatures of fractionalized excitations at two different deconfined quantum critical points(DQCPs)in an S=1/2 spin chain using the time evolution of infinite matrix product...
