Finite Temperature Density Matrix Renormalization using an enlarged Hilbert space
A. E. Feiguin, Steven R. White
We apply a generalization of the time-dependent DMRG to study finite temperature properties of several quantum spin chains, including the frustrated model. We discuss sev…

Time-step targetting methods for real-time dynamics using DMRG
Adrian E. Feiguin, Steven R. White
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 system…
