On the Virial Theorem in Quantum Mechanics
Communications in Mathematical Physics, 1999The authors review several versions of the quantum mechanical virial theorem that exist in the literature. By considering an explicits situation, it is shown that the version contained in the book of \textit{H. L. Cycon}, \textit{R. G. Froese}, \textit{W. Kirsch} and \textit{B.

The virial theorem with periodic boundary conditions
Chemical Physics Letters, 2023 4 figuresInternational audienceThe virial theorem relates averages of kinetic energy and forces in confined systems. It is widely used to relate stresses in molecular simulation as measured at a boundary and in the interior of a system.

Generalizations of the Virial Theorem
American Journal of Physics, 1957This paper is a review of three generalizations of the classical virial theorem of Clausius, the first to a continuous distribution of charge and mass moving with relativistic velocity and its associated electromagnetic field, the second to a single Dirac particle in an external electromagnetic field, and the third to a quantum-mechanical system of ...

Virial theorem from action principles
Annals of PhysicsThe virial theorem is derived from the action principle and variational method in classical and quantum mechanics by exploiting the scale invariance of the action and the Hamiltonian operator.

While the virial theorem plays a relatively minor role generally in physics, it is of vital importance for the understanding of stars. It connects two important energy reservoirs of a star and allows predictions and interpretations of certain evolutionary phases.

ABS>A generalization of the Chandrasekhar-Fermi virial theorem is outlined to include plasmas. From this generalization it may be concluded that in the absence of confining gravitational fields, self-confinement of plasmas cannot be achieved. (B.O.G.)

The Buchdahl bound denotes the geometrical Virial theorem
Annals of PhysicsIn this paper, we geometrically establish yet another correspondence between Newtonian mechanics and general relativity by connecting the Buchdahl bound and the Virial theorem. Buchdahl stars are defined by the saturation of the Buchdahl bound, $\Phi(R) \
