Phys. Rev. Lett. 93, 076401 (2004) [4 pages]Real-Time Evolution Using the Density Matrix Renormalization GroupReceived 17 March 2004; published 10 August 2004 We describe an extension to the density matrix renormalization group method incorporating real-time evolution. Its application to transport problems in systems out of equilibrium and frequency dependent correlation functions is discussed and illustrated in several examples. We simulate a scattering process in a spin chain which generates a spatially nonlocal entangled wave function. © 2004 The American Physical Society URL:
