Test of a variational method applied to disordered systems
Test of a variational method applied to disordered systems is a scholarly work, published in 1979 in ''Physical Review B''. The main subjects of the publication include simple, physics, particle system, statistical physics, computer science, Variational method, stochastic thermodynamics, quantum biology, range, applied mathematics, critical phenomena, and partition function. Using a wide range of model parameters, it is found that the variational method yields results which are an improvement over those of conventional methods and which are exact in all extreme cases.
