Off equilibrium dynamics in the 3d-XY system
Stephane Abriet, Dragi Karevski
We investigate through Monte Carlo simulations the non-equilibrium behaviour of the three-dimensional XY-model quenched from a high temperature state to its ferromagnetic and criti…

Off equilibrium dynamics in 2d-XY system
Stephane Abriet, Dragi Karevski
We study the non-equilibrium time evolution of the classical XY spin model in two dimensions. The two-time autocorrelation and linear response functions are considered for systems…

Off equilibrium dynamics in disordered quantum spin chain
Stéphane Abriet, Dragi Karevski
We study the non-equilibrium time evolution of the average transverse magnetisation and end-to-end correlation functions of the random Ising quantum chain. Starting with fully magn…
