Re: How to realize SU(2) symmetric DMRG?
Hi Johannes, Thank you so much for your response. This really helps a lot! You are right that I did not open any charge conservation here, and that might be the key reason why my DMRG is so slow. Since several months before when I first start using DMRG to calculate the energy gap of 1D chain AKLT H...

How to realize SU(2) symmetric DMRG?
Hi everyone, I am working on calculating the energy gap of spin-3/2 AKLT Hamiltonian on hexagonal lattice. However, on my group computer server, I am only able to run on a 2*3 hexagonal lattice (12 sites) with periodic boundary conditions. To be specific, I used CouplingModel and MPOModel to constru...
