Time-dependent gravitational background is well-known as a theoretical laboratory for quantum mechanical particle production. In the present analysis, we explore such production in a time-dependent analog system. This is the follow-up of our earlier study on the Sonoluminescence phenomenon, which is modelled in terms of analog geometry coupled with the electromagnetic field exhibiting the quantum production of photons. In the same analog geometry, we studied fermion production. Although fermions have not been observed yet in the sonoluminescence experiment, we have shown here that such a system can produce a repeated flux of fermions via the parametric resonance from a quantum vacuum. Our analysis seems to suggest that in the laboratory setup, time-dependent analog systems could be an interesting playground where phenomena of quantum mechanical particle production can be observed.
