Abstract:
The equivalence between canonical and grand canonical constraints near a random fixed point in a critical disordered system is confirmed by means of Monte Carlo simulations. The slow approach to the asymptotic distribution for canonical averaging given by the L((alpha/nu)(random)) term is overcome by simulating long range correlated diluted Ising systems with (alpha/nu)(random)=(a-d) for the particular values a=2 (linear defects) and d=3 (three dimensional systems).

Stability of Equilibrium Configuration
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...
