A simple way to avoid metastable configurations in the density-matrix renormalization-group algorithms
spin model DMRG spin-1
2010/7/8
We use the spin-1 Heisenberg chain with periodic boundary conditions to ilustrate that the systems get stuck in metastable configurations only when the density-matrix renormalization-group algorithm s...
Subtractive Renormalization of One-Pion-Exchange and Contact Interactions
Subtractive Renormalization One-Pion-Exchange Contact Interactions
2010/10/15
A recursive subtractive renormalization of the scattering equation is applied to the nucleon-nucleon 1S0 channel with one-pion-exchange plus derivative contact interactions. This method can be easily ...
