Exploring Interacting Topological Insulators with Ultracold Atoms: the Synthetic Creutz-Hubbard Model
J. Jünemann, A. Piga, S. -J. Ran +3
Understanding the robustness of topological phases of matter in the presence of strong interactions, and synthesising novel strongly-correlated topological materials, lie among the…
Criticality in Two-Dimensional Quantum Systems: Tensor Network Approach
Shi-Ju Ran, Cheng Peng, Wei Li +2
Determination and characterization of criticality in two-dimensional (2D) quantum many-body systems belong to the most important challenges and problems of quantum physics. In this…
Studying Criticality and Excitations of One Dimensional Systems by Time Matrix Product States
Emanuele Tirrito, Luca Tagliacozzo, Maciej Lewenstein +1
(Please refer to arXiv:1810.08050, which has completely different aims but contains all the main contents of this paper) In this work, we propose to access the information of criti…
An efficient perturbation theory of density matrix renormalization group
Emanuele Tirrito, Shi-Ju Ran, Andrew J. Ferris +2
Density matrix renormalization group (DMRG) is one of the most powerful numerical methods available for many-body systems. In this work, we develop a perturbation theory of DMRG (P…
