Short-time dynamics of a family of XY noncollinear magnets
S. Bekhechi, B. W. Southern, A. Peles +1
Critical scaling and universality in the short-time dynamics for antiferromagnetic models on a three-dimensional stacked triangular lattice are investigated using Monte Carlo simul…
Critical properties of a continuous family of XY noncollinear magnets
A. Peles, B. W. Southern, B. Delamotte +2
Monte Carlo methods are used to study a family of three dimensional XY frustrated models interpolating continuously between the stacked triangular antiferromagnets and a variant of…
Frustrated Heisenberg Antiferromagnets between d=2 and d=3
A. Peles, B. W. Southern
The antiferromagnetic Heisenberg model on a stacked triangular geometry with a finite number of layers is studied using Monte Carlo methods. A topological phase transition occurs a…
Damage spreading in two dimensional geometrically frustrated lattices: the triangular and kagome anistropic Heisenberg model
S. Bekhechi, B. W. Southern
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 triangula…
Off Equilibrium Study of the Fluctuation-Dissipation Relation in the Easy-Axis Heisenberg Antiferromagnet on the Kagome Lattice
S. Bekhechi, B. W. Southern
Violation of the fluctuation-dissipation theorem (FDT) in a frustrated Heisenberg model on the Kagome lattice is investigated using Monte Carlo simulations. The model exhibits glas…
