Density Matrix Renormalization Group Approach to an Asymptotically Free Model with Bound States
Density Matrix Renormalization Group Approach to an Asymptotically Free Model with Bound States
We apply the density matrix renormalization group (DMRG) method to the two-dimensional delta function potential which is a simple quantum mechanical model with asymptotic freedom and formation of bound states. The system block and the environment block of the DMRG contain the low energy and high energy degrees of freedom, …
