The ring approximation has been used in the kinetic theory of hard sphere fluids to investigate non-equilibrium phenomena depending on dynamic correlations, not included in the Boltzmann or Enskog equations. We show that ...

It ts known that Tsallis’ q-non-additivity entails hidden correlations. It has also been shown that even for a monoatomic gas, both the q-partition function Z and the mean energy 〈U〉 diverge and, in particular, exhibit ...

A new distribution for systems of particles in equilibrium obeying the exclusion of correlated states is presented following Haldane's state counting. It relies upon an ansatz to deal with the multiple exclusion that takes ...

In theories of modified gravity with the chameleon screening mechanism, the strength of the fifth force depends on environment. This induces an environment dependence of structure formation, which differs from Lambda-col ...
