The high Tc is obtained by tuning the chemical potential near the bottom of the nth subband at a \"shape resonance\", in a range, whithin the energy cutoff for the pairing interaction. The resonance for the gap at the nth \"shape resonance\" is studied for a free electron gas in the BCS approximation as a function of the stripe width L, and of the number of ","authors_text":"Alessandra Lanzara, Andrea Perali, Antonio Bianconi, Naurang L.
