In Praise of Slowness
Roland Lehoucq, Etienne Ligout
While speed is an ubiquitous concept in physics, its inverse - known as slowness - sometimes proves more relevant. We discuss some case studies within classical physics where such…
Unified presentation of four fundamental inequalities
Joseph Lajzerowicz, Roland Lehoucq, François Graner
We suggest an unified presentation to teach fundamental constants to graduate students, by introducing four lower limits to observed phenomena. The reduced Planck constant …
Vacuum friction on a rotating pair of atoms
Hervé Bercegol, Roland Lehoucq
Zero-point quantum fluctuations of the electromagnetic vacuum create the widely known London-van der Waals attractive force between two atoms. Recently, there was a revived interes…
New constraints on the primordial black hole number density from Galactic gamma-ray astronomy
R. Lehoucq, M. Casse, J. -M. Casandjian +1
Primordial black holes are unique probes of cosmology, general relativity, quantum gravity and non standard particle physics. They can be considered as the ultimate particle accele…
A new analysis of Poincaré dodecahedral space model
S. Caillerie, M. Lachièze-Rey, J. -P. Luminet +3
The full three-year WMAP results (WMAP3) reinforce the absence of large-angle correlations at scales greater than 60 degrees. The Poincare dodecahedral space (PDS) model model, whi…
Constraining Cosmic Topology with CMB Polarization
Alain Riazuelo, Samuel Caillerie, Marc Lachièze-Rey +2
Multiply connected space sections of the universe on a scale smaller than the horizon size can leave an imprint on cosmic microwave background polarization maps, in such a way that…
