Density Matrix Renormalization Group Method for 2D Classical Models
Synopsis The density matrix renormalization group (DMRG) method is applied to the interaction round a face (IRF) model. When the transfer matrix is asymmetric, singular-value decomposition of the density matrix is required. A trial numerical calculation is performed on the square lattice Ising model, which is a special case of the IRF model.
متن کاملComment on “ Density - matrix renormalization - group method for excited states ”
In a recent paper (Phys. Rev. B 59, 9699 (1999)), Chandross and Hicks claim to present a new density matrix renormalisation group (DMRG) method for dealing with excited states of quantum lattice models. The proposed improvement to the DMRG—the inclusion of excited state wave functions in addition to the ground state in the density matrix when calculating excitations— is in fact standard pratice...

متن کاملDensity-matrix renormalization group algorithms
The Density Matrix Renormalization Group (DMRG) was developed by White [1, 2] in 1992 to overcome the problems arising in the application of real-space renormalization groups to quantum lattice many-body systems in solid-state physics. Since then the approach has been extended to a great variety of problems in all fields of physics and even in quantum chemistry. The numerous applications of DMR...
متن کاملThe density-matrix renormalization group
The density-matrix renormalization group sDMRGd is a numerical algorithm for the efficient truncation of the Hilbert space of low-dimensional strongly correlated quantum systems based on a rather general decimation prescription. This algorithm has achieved unprecedented precision in the description of one-dimensional quantum systems. It has therefore quickly become the method of choice for nume...
