Signatures of Dirac Cones in a DMRG Study of the Kagome Heisenberg Model
Signatures of Dirac Cones in a DMRG Study of the Kagome Heisenberg Model
The antiferromagnetic spin-$1/2$ Heisenberg model on a kagome lattice is one of the most paradigmatic models in the context of spin liquids, yet the precise nature of its ground state is not understood. We use large scale density matrix normalization group simulations (DMRG) on infinitely long cylinders and find indications …
