Resumen:

The 18SIB04 QuantumPascal EMPIR project aims to achieve quantum-based pressure standards. One of the most promising ways of achieving this goal is the use of a Fabry-Perot interferometer for measuring the refractivity of the involved gas.
The refractivity and gas pressure are connected by the Claussius-Mossotti and Lorenz-Lorentz formal relations. However, these relations are based on “ideal assumptions”. The main scope of this research is how to solve this problem minimizing the use of the refractivity virial expansion by a parameter modifying the Lorenz-Lorentz relation. This methodology increases the physical quantum knowledge of the involved gases and develops a new procedure for determining the gas pressure from refractivity measurements.
