Abstract

The information contained in the density matrix allows one to truncate a large phononic Hilbert space without significant loss of accuracy. Thus, it is possible to study electron-phonon systems numerically with great accuracy. Coupled to a powerful numerical methods such as DMRG these approaches enable us to treat very large systems. These techniques could greatly improve our capability to perform numerical studies of many problems, such as electron-phonon systems, which involve a large or infinite Hilbert space.
