Time-step targetting methods for real-time dynamics using DMRG
arXiv:cond-mat/0502475 · doi:10.1103/PhysRevB.72.020404
Abstract
We present a time-step targetting scheme to simulate real-time dynamics efficiently using the density matrix renormalization group (DMRG). The algorithm works on ladders and systems with interactions beyond nearest neighbors, in contrast to existing Suzuki-Trotter based approaches.
