Large- and tensor-network methods for strongly-interacting topological insulators
E. Tirrito, S. Hands, A. Bermudez
The study of correlation effects in topological phases of matter can benefit from a multidisciplinary approach that combines techniques drawn from condensed matter, high-energy phy…
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…
