Classical Ring-exchange Processes on the Triangular Lattice
June Seo Kim, Jung Hoon Han
The effects of the ring-exchange Hamiltonian H_3 = J_3 sum_{<ijk>} (S_i * S_j) (S_i * S_k) on the triangular lattice are studied using classical Monte Carlo simulations. Each spin…

Effective Vortex Mass from Microscopic Theory
Jung Hoon Han, June Seo Kim, Min Jae Kim +1
We calculate the effective mass of a single quantized vortex in the BCS superconductor at finite temperature. Based on effective action approach, we arrive at the effective mass of…
