Abstract: In this note, we give an alternative proof of the Virial Theorem for the Dirac equation perturbed with a Coulomb-like potential, result which goes back to Albeverio (Ann Phys 71:167–276, 1972), Kalf (J Funct Anal… read more here.

DOI: 10.1088/1751-8121/accfd3
Abstract: We formulate and study a generalized virial theorem for contact Hamiltonian systems. Such systems describe mechanical systems in the presence of simple dissipative forces such as Rayleigh friction, or the vertical motion of a particle… read more here.
