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