Abstract

We discuss the normal state of a fermionic system in an idealized PSEUDOGAP REGIME, $k_{B} T_{c} < k_{B} T << ∣Δ∣ << E_{F}$ . Stable Cooper pairs induce a pseudogap of width $∣Δ∣$ in the fermion energy spectrum. Near two dimensions, we find a Bose-like condensation temperature in this predominantly fermionic system.
