DMRG+QTT
19/11/2010
DMRG (Density Matrix Renormalization Group) is a very efficient algorithm for computation of low-lying eigenstates of quantum spin systems. QTT (Quantics Tensor Train) consists in tensorization of one-dimensional objects (i.e. vectors of values of function on a grid with 2^d points) into a d-dimensional tensor, and application of Tensor Train (TT) format to such tensor. What do they have in common? Check our new paper, DMRG+QTT approach to high-dimensional quantum molecular dynamics
