Dark matter casts light on the early Universe

Abstract We show how knowledge of the cold dark matter (CDM) density can be used, in conjunction with measurements of the parameters of a scenario for beyond the Standard Model (BSM) physics, to provide information about the evolution of the Universe before Big Bang Nucleosynthesis (BBN).As examples of non-standard evolution, NAIL LACQUER 1972 we c

Superconductor spintronics: modeling spin and charge accumulation in out-of-equilibrium NIS junctions subjected to Zeeman magnetic fields

We study the spin and charge accumulation in Calculator a superconductor when a normal-superconductor tunnel junction is subjected to a Zeeman magnetic field and taken out of equilibrium by applying either a DC or AC voltage bias.We focus on a configuration which allows one to measure non-locally the spin-accumulation using a second ferromagnetic e
