Abstract
The present work analyses the consequences of the gravitomagnetic effect of the Earth upon a bosonic gas in which the corresponding atoms have a nonvanishing orbital angular momentum. Concerning the ground state of the Bogoliubov space of this system we deduce the consequences, on the pressure and on the speed of sound, of the gravitomagnetic effect. We prove that the effect on a single atom is very small, but we also show that for some thermodynamical properties the consequences scale as a nontrivial function of the number of particles.Keywords
