Witryna31 gru 1990 · These lectures consider the kinetics of phase changes, induced by a sudden change of external thermodynamic parameters. E.g., we treat a system with a second-order transition at a critical temperature Tc (Fig. 1, left part). For T0 > Tc the system is disordered, while for T < Tc there is an order parameter ± ψ (implying one … WitrynaAbstract. Charged domain walls in ferroelectrics hold great promise for the design of novel electronic devices due to their enhanced local conductivity. In fact, charged domain walls show unique properties including the possibility of being created, moved and erased by an applied voltage. Here, we demonstrate that the charged domain …

We discuss several problems concerning domain walls in the spin Ising model at zero temperature in a … WitrynaThe Boltzmann weight for any dual link with a domain wall present is e 2 J relative to the link without the domain wall. In the simplest case where the coupling is independent of link, J = J, the two-dimensional Ising partition function Z= X ˙ i= 1 e J P ˙ i˙ j can be rewritten in terms of domain walls as Z= e JN X ˙ i= 1 e 2 ... brian pettifer notary
