In ﬁnite model space suitable for many-body calculations via the no-core shell model (NCSM), I illustrate the direct application of the eﬀective ﬁeld theory (EFT) principles to solving the many-body Schrödinger equation. Two diﬀerent avenues for ﬁxing the low-energy constants naturally arising in an EFT approach are discussed. I review results for both nuclear and trapped atomic systems, using eﬀective theories formally similar, albeit describing diﬀerent underlying physics.
