Title: QUO VADIS DMRG?

Abstract:

The density-matrix renormalization group (DMRG), based on matrix product 
states (MPS), is arguably the most successful group of algorithms in the 
tensor network framework and has established itself as the leading 
method for one-dimensional model Hamiltonians in equilibrium and to a 
large extent also out of equilibrium. The question is, of course, can we 
go beyond that? In this talk, I want to review progress made in the 
development of time-dependent simulations over the last few years, and 
show how it has been instrumental in allowing powerful applications in 
the field of more realistic material simulations for correlated matter 
when combined with the dynamical mean-field theory (DMFT). Finally, I 
want to show how automated modifications of the underlying 
single-particle bases allow much more powerful simulations for 
two-dimensional model Hamiltonians such as the Hubbard model, a 
development which is still in its early stages.
