Superconductivity in the Repulsive Hubbard Model
The two-dimensional repulsive Hubbard model has been investigated by a variety of methods, from small to large U . Superconductivity with d-wave symmetry is consistently found close to half filling. After a brief review of the various methods a variational many-electron state is discussed in more detail. This trial state is a natural extension of the Gutzwiller ansatz and provides a substantial...
متن کاملStrong coupling superconductivity via an asymptotically exact renormalization-group framework
A renormalization-group approach for interacting electrons, which are also coupled to phonons was recently developed [1]. The method is described here in some detail, including the large-N analysis which shows that the theory is asymptotically exact and from which Migdal’s theorem follows as a consequence. We present analytical and numerical results for the case of an isotropic Fermi surface an...
متن کاملN-chain Hubbard model in weak coupling
We present a systematic weak-coupling renormalization group ~RG! technique for studying a collection of N coupled one-dimensional interacting electron systems, focusing on the example of N-leg Hubbard ladders. For N52,3, we recover previous results, and find that also more generally broad regions of the phase space of these models are unstable to pairing, usually with approximate d-wave symmetr...
متن کاملColor superconductivity in weak coupling
Cooper’s theorem [1–3] implies that if there is an attractive interaction in a cold Fermi sea, the system is unstable with respect to formation of a particle-particle condensate. In QCD, single-gluon exchange between quarks of different color generates an attractive interaction in the color-antitriplet channel [4]. Thus, it appears unavoidable that color superconductivity occurs in dense quark ...
متن کاملPhase diagram of the extended Hubbard model at weak coupling.
The Hubbard model including nearest neighbor interaction is studied at T50 on a d-dimensional hypercubic lattice (d@1) close to half filling. For the model in d5` we derive the exact result that the ground state at weak coupling is phase separated. Results for lower dimensions are then derived in a 1/d expansion. To obtain these results we first consider possible second order transitions. One t...
