Ultracold atomic systems have emerged as strong contenders amongst the various quantum systems relevant for developing and implementing quantum technologies due to their enhanced control and flexibility of the operating conditions. In this thesis, we explore persistent currents generated in a ring-shaped quantum gas of strongly interacting N-component fermions, specifically the so-called SU(N) fermions. Our results, apart from being a relevant contribution to many-body physics, prove the `primum mobile' for a new concept of matter-wave circuits based on SU(N) fermionic platforms, opening an exciting chapter in the field of atomtronics. Indeed, the specific properties of quantization are expected to provide the core to fabricate quantum devices with enhanced sensitivity like interferometers. At the same time, SU(N) fermionic circuits show promise in engineering cold atoms quantum simulators with this artificial fermionic matter.
