Strategy for Finding the Lowest Energy State in each Sz sectors
Posted: 30 Oct 2025, 05:59
Hi,
Can anyone please describe what the best strategy is for finding the lowest energy state for each Sz sector? For example, I am interested in a finite 2d triangular lattice with NN interaction with Heisenberg Antiferromagnetic coupling. I guess conserving the quantum number will increase the additional convergence issue during the DMRG run.
