Cooper pair delocalization in disordered media
M. A. N. Araujo, M. Dzierzawa, C. Aebischer +1
We discuss the effect of disorder on the coherent propagation of the bound state of two attracting particles. It is shown that a result analogous to the Anderson theorem for dirty…

Instabilities of the Hubbard chain in a magnetic field
J. M. P. Carmelo, F. Guinea, P. D. Sacramento
We find and characterize the instabilities of the repulsive Hubbard chain in a magnetic field by studing all response functions at low frequency ωand arbitrary momentum. The instab…

Complete Pseudohole and Heavy-Pseudoparticle Operator Representation for the Hubbard Chain
J. M. P. Carmelo, N. M. R. Peres
We introduce the pseudohole and heavy-pseudoparticle operator algebra that generates all Hubbard-chain eigenstates from a single reference vacuum. In addition to the pseudoholes al…
