Splitting of the ground state manifold of classical Heisenberg spins as couplings are varied
Samarth Chandra
We construct clusters of classical Heisenberg spins with two-spin -type interactions for which the ground state manifold consists of disconnected pieces. We ex…

Classical Heisenberg spins on a hexagonal lattice with Kitaev couplings
Samarth Chandra, Kabir Ramola, Deepak Dhar
We analyse the low temperature properties of a system of classical Heisenberg spins on a hexagonal lattice with Kitaev couplings. For a lattice of 2N sites with periodic boundary c…
