0 Superconducting Phase with Fractional Vortices in the Frustrated Kagome Wire Network at f = 1 / 2

In classical XY kagome antiferromagnets, there can be a novel low temperature phase where ψ3 = ei3θ has quasi-long-range order but ψ is disordered, as well as more conventional antiferromagnetic phases where ψ is ordered in various possible patterns (θ is the angle of orientation of the spin). To investigate when these phases exist in a physical system, we study superconducting kagome wire netw...

Damage spreading in two dimensional geometrically frustrated lattices: the triangular and kagome anisotropic Heisenberg model

The technique of damage spreading is used to study the phase diagram of the easy axis anisotropic Heisenberg antiferromagnet on two geometrically frustrated lattices. The triangular and kagome systems are built up from triangular units that either share edges or corners respectively. The triangular lattice undergoes two sequential Kosterlitz-Thouless transitions while the kagome lattice undergo...
