• Title: "Melting of three-sublattice order in triangular and Kagome Ising anti-ferromagnets with further neighbour couplings"
• Abstract:   Under second and third nearest neighbour ferromagnetic couplings of the constituent Ising spins, triangular and Kagome lattice antiferromagnets develop long-range order that distinguishes the three sublattices of the underlying triangular Bravais lattice. In this talk I will chalk out two cluster algorithms which we developed for such frustrated systems and discuss the various melting scenarios of the long-range order in both the lattices. I will also discuss the performance and statistics of the algorithms, and show their connection to Brownian motion in a logarithmic potential.
