The relation between the canonical Hamilton-Jacobi equation and the covariant Hamilton-Jacobi equation for Maxwell's electrodynamics
Monika E. Pietrzyk, Cécile Barbachoux, Joseph Kouneiher
The aim of this paper is to understand the relation between the canonical Hamilton-Jacobi equation for Maxwell's electrodynamics, which is an equation with variational derivatives…
On the covariant Hamilton-Jacobi formulation of Maxwell's equations via the polysymplectic reduction
Monika E. Pietrzyk, Cécile Barbachoux, Igor V. Kanatchikov +1
The covariant Hamilton-Jacobi formulation of Maxwell's equations is derived from the first-order (Palatini-like) Lagrangian using the analysis of constraints within the De~Donder-W…
On the Covariant Hamilton-Jacobi Equation for the Teleparallel Equivalent of General Relativity
Monika E. Pietrzyk, Cécile Barbachoux
The covariant Hamilton-Jacobi equation for the Teleparallel Equivalent of General Relativity is derived based on the analysis of the second-class constraints within the covariant H…
Model of collimated jets with high energy particles
C. Barbachoux, J. Gariel, G. Marcilhacy +1
The increasing data set of precise observations of very energetic and collimated jets, with black hole (BH) as putative central engine, at different astrophysical scales and in var…
Cosmological energy in a thermo-horizon and the first law
Cécile Barbachoux, Jérome Gariel, Gérard Le Denmat
We consider a cosmological horizon, named thermo-horizon, to which are associated a temperature and an entropy of Bekenstein-Hawking and which obeys the first law for an energy flo…
Cosmological evolution with a logarithmic correction in the dark energy entropy
Cécile Barbachoux, Jérome Gariel, Gérard Le Denmat
In a thermodynamical model of cosmological FLRW event horizons for the dark energy (DE), we consider a logarithmic corrective term in the entropy to which corresponds a new term in…
