Renormalization-group approach to superconductivity: from weak to strong electron-phonon coupling
S. -W. Tsai, A. H. Castro Neto, R. Shankar +1
We present the numerical solution of the renormalization group (RG) equations derived in Ref. [1], for the problem of superconductivity in the presence of both electron-electron an…

Renormalization Group Approach to Strong-Coupled Superconductors
S. -W. Tsai, A. H. Castro Neto, R. Shankar +1
We develop an asymptotically exact renormalization group (RG) approach that treats electron-electron and electron-phonon interactions on equal footing. The approach allows an unbia…
