Microcanonical finite-size scaling

In the microcanonical ensemble, suitably defined observables show nonanalyt icities and power-law behavior even for finite systems; For these observabl es, a microcanonical finite-size scaling theory is established and combined with the experimentally observed power-law behavior. Scaling laws are obta ined which relate exponents of the finite system and critical exponents of the infinite system to the system-size dependence of the affiliated microca nonical observables.
