Historical Hamiltonian Dynamics: symplectic and covariant
M Lachieze-Rey
This paper presents a "historical" formalism for dynamical systems, in its Hamiltonian version (Lagrangian version was presented in a previous paper). It is universal, in the sense…
Historical Lagrangian Dynamics
Marc Lachieze-Rey
This paper presents (in its Lagrangian version) a very general "historical" formalism for dynamical systems, including time-dynamics and field theories. It is based on the universa…
In search of relativistic time
Marc Lachieze-Rey
This paper explores the status of some notions which are usually associated to time, like datations, chronology, durations, causality, cosmic time and time functions in the Einstei…
Effect of model-dependent covariance matrix for studying Baryon Acoustic Oscillations
A. Labatie, J. -L. Starck, M. Lachièze-Rey
Large-scale structures in the Universe are a powerful tool to test cosmological models and constrain cosmological parameters. A particular feature of interest comes from Baryon Aco…
Detecting Baryon Acoustic Oscillations
A. Labatie, J. -L. Starck, M. Lachièze-Rey
Baryon Acoustic Oscillations are a feature imprinted in the galaxy distribution by acoustic waves traveling in the plasma of the early universe. Their detection at the expected sca…
A new look at Lorentz-Covariant Loop Quantum Gravity
Marc Geiller, Marc Lachieze-Rey, Karim Noui
In this work, we study the classical and quantum properties of the unique commutative Lorentz-covariant connection for loop quantum gravity. This connection has been found after so…
