Scalar QED effective action in dS: implications for primordial magnetogenesis and the running of coupling constants
Ehsan Bavarsad, Sang Pyo Kim, Clément Stahl +1
Particles creation and vacuum polarization under the influence of both an electromagnetic field and a de~Sitter (dS) spacetime nonperturbatively probes quantum electrodynamics (QED…
Massless fermionic current of Schwinger pairs in 3D de Sitter spacetime
Manizheh Botshekananfarda, Clément Stahl
Pair creation from the vacuum in the presence of a U(1) gauge field in de Sitter spacetime provides an important setting for exploring quantum field theory in curve…
Simulating the Universe from the cosmological horizon to halo scales
Thomas Montandon, Oliver Hahn, Clément Stahl
Ultra-large scales close to the cosmological horizon will be probed by the upcoming observational campaigns. They hold the promise to constrain single-field inflation as well as ge…
Hydrodynamical simulations of galaxy formation with non-Gaussian initial conditions
Clément Stahl, Yohan Dubois, Benoit Famaey +4
Collisionless simulations of structure formation with significant local primordial non-Gaussianities at Mpc scales have shown that a non-Gaussian tail favouring underdensities, wit…
Relativistic matter bispectrum of cosmic structures on the light cone
Thomas Montandon, Julian Adamek, Oliver Hahn +4
Upcoming surveys of cosmic structures will probe scales close to the cosmological horizon, which opens up new opportunities for testing the cosmological concordance model to high a…
Dipolar dark matter simulations on galaxy scales with the RAMSES code
Clément Stahl, Benoit Famaey, Guillaume Thomas +2
We numerically explore on galaxy scales the Dipolar dark matter (DM) model based on the concept of gravitational polarization. This DM model has been proposed as a natural way to r…
