Violation of the virial theorem and generalized equipartition theorem for logarithmic oscillators serving as a thermostat [PDF]
Scientific Reports, 2017 A logarithmic oscillator has been proposed to serve as a thermostat recently since it has a peculiar property of infinite heat capacity according to the virial theorem.

Astrophysics and Space Science, 1976 A new type of cosmic virial theorem is derived, representing a relation among the two-point and three-point galaxy correlation functions and the mean square relative peculiar velocity 〈v 2(r)〉 averaged over pairs of galaxies separated by distancer. The two correlation functions seem to be fairly well known, but 〈v 2(r)〉 at best is only very roughly ...

Gravitational Hamiltonian Systems and the Retarded Gravity Inequality [PDF]
EntropyGravity and electromagnetic interactions are the only fundamental physical interactions (outside the nuclear domain). In this work, we shall concentrate on Hamiltonians containing gravitational interaction, which according to general relativity must be ...

The Fractional Virial Theorem [PDF]
Fractional Differential Calculus, 2011 Summary: Fractional calculus is an emerging field and has many applications in several fields of science and engineering. One of the major issues in this field is to apply this type of calculus to the real world applications. In this paper, the fractional generalization of the classical virial theorem is presented.

Variational Methods for Atoms and the Virial Theorem
Atoms, 2022 In the case of the one-electron Dirac equation with a point nucleus, the virial theorem (VT) states that the ratio of the kinetic energy to potential energy is exactly −1, a ratio that can be an independent test of the accuracy of a computed solution ...

Virial theorem in scalar tensor fourth order gravity
European Physical Journal C: Particles and Fields, 2021 In this paper, we study, in the Newtonian limit, the virial theorem in the context of a scalar tensor fourth order gravity. In particular, we show, that for a isolated galaxy in viral equilibrium, a specific class of scalar tensor fourth order gravity, i.

Virial theorems and virial stresses of micropolar media [PDF]
Journal of Micromechanics and Molecular Physics, 2021 A generalization of virial theorems and virial stresses to micropolar continuum mechanics is explored. The linear momentum balance in dyadic product with translation leads to (i) the first virial theorem of micropolar continuum mechanics involving the infinite-time limit of the kinetic translational energy and (ii) a classical formula for computing ...
