Extensions of DMRG
In 2004 the time-evolving block decimation method was developed to implement real time evolution of Matrix Product States. The idea is based on the classical simulation of a quantum computer. Subsequently, a new method was devised to compute real time evolution within the DMRG formalism - See the paper by A. Feiguin and S.R. White .
In recent years, some proposals to extend the method to 2D and 3D have been put forward, extending the definition of the Matrix Product States. See this paper by F. Verstraete and I. Cirac, .

Famous quotes containing the words extensions of and/or extensions:
“The psychological umbilical cord is more difficult to cut than the real one. We experience our children as extensions of ourselves, and we feel as though their behavior is an expression of something within us...instead of an expression of something in them. We see in our children our own reflection, and when we don’t like what we see, we feel angry at the reflection.”
—Elaine Heffner (20th century)
