Abstract
We show that for a one-dimensional electron gas with strong repulsive electron-electron interactions and a weak retarded attractive interaction, superconducting fluctuations can occur at high temperatures. The dominant driving force for these fluctuations is the repulsive interactions! Although the results are for a one-dimensional model, a strong analogy exists between our results and the short-ranged resonating-valence-bond picture of superconductivity.Keywords
