Cosmological backgroung torsion limits from Lorentz violation
Cosmological limits on Lorentz invariance breaking in Chern-Simons (3 + 1) − dimensional electrodynamics are used to place limits on torsion. Birefrigence phenomena is discussed by using extending the propagation equation to Riemann-Cartan spacetimes instead of treating it in purely Riemannian spaces. The parameter of Lorentz violation is shown to be proportional to the axial torsion vector whi...
متن کاملPost{newtonian Cosmological Dynamics
The non{linear dynamics of self{gravitating collisionless matter with vanishing vorticity is studied in a general relativistic framework, using synchronous and comoving (i.e. Lagrangian) coordinates. Writing the equations in terms of the metric tensor of the spatial sections orthogonal to the uid ow allows an unambiguous expansion in inverse powers of the speed of light. The Newtonian and post{...
متن کاملMultiscale cosmological dynamics
Multiscale systems are characterized by intricate dynamics which couple several different time or space scales. Nevertheless, in many instances it is possible to obtain an effective dynamics governing the evolution of a multiscale system on a larger scale by averaging the full exact dynamics on smaller scales. Examples range from economics [1] to biophysics [2] and include turbulence [3] and qu...
متن کاملTorsion dynamics of molecular systems.
Based on the concept of free energy, we derive a Hamiltonian formulation for molecular dynamics in torsion space. The appropriate reaction coordinates for the free energy calculations are deened in terms of soft constraints as introduced by B.R. in the context of molecular dynamics. We consider a few simpliications that allow one to calculate the free energy analytically and to write the corres...
متن کامل3 Photon mass and Cosmological constant bounds from spacetime torsion
Photon mass and Cartan contortion bounds recently obtained from tiny Lorentz violation observations in cosmology are used to find a limit of λ ≤ 10 −4 α for the massive photon-torsion dimensionless coupling. Here α represents the fine-structure constant. A gauge invariant Proca electrodynamics in spacetime endowed with torsion in de Sitter spacetime is used to obtain an upper bound for the pres...
