SUMMARY
The ground state energy of a system of 2N fermions confined in a harmonic oscillator potential U(x) = 1/2(k)(x²) is determined using the formula E = 1/2 ℏω. The potential V(x) is expressed as V(x) = 1/2m(ω²)(x²). The fermionic nature of the particles implies that they obey the Pauli exclusion principle, affecting how they populate the available energy states in the system.
