Variation of mass in primordial nucleosynthesis as a test of Induced Matter Brane Gravity
S. Jalalzadeh, A. M. Yazdani
The variation of mass in induced matter theory using Ceroch-Stewart-Walter perturbations of submanifolds [1] is redefined. It is shown that the deviation of primordial Helium produ…
Coulomb scattering for scalar field in Scr\" odinger picture
Crucean Cosmin, Racoceanu Radu, Pop Adrian
The scattering of a charged scalar field on Coulomb potential on de Sitter space-time is studied using the solution of the free Klein-Gordon equation. We find that the scattering a…
Geodesic Equations on Diffeomorphism Groups
Cornelia Vizman
We bring together those systems of hydrodynamical type that can be written as geodesic equations on diffeomorphism groups or on extensions of diffeomorphism groups with right invar…
The quantum theory of scalar fields on the de Sitter expanding universe
Ion I. Cotaescu, Cosmin Crucean, Adrian Pop
New quantum modes of the free scalar field are derived in a special time-evolution picture that may be introduced in moving charts of de Sitter backgrounds. The wave functions of t…
Dirac-Coulomb scattering with plane wave energy eigenspinors on de Sitter expanding universe
Ion I. Cotaescu, Crucean Cosmin
The lowest order contribution of the amplitude of Dirac-Coulomb scattering in de Sitter spacetime is calculated assuming that the initial and final states of the Dirac field are de…
Generalized versus selected descriptions of quantum LC - circuits
E. Papp, C. Micu, O. Borchin +1
Proofs are given that the quantum-mechanical description of the LC -circuit with a time dependent external source can be readily established by starting from a more general discret…
