Composite pairing in a mixed-valent two-channel Anderson model
Using a two-channel Anderson model, we develop a theory of composite pairing in the 115 family of heavy fermion superconductors that incorporates the effects of f -electron valence fluctuations. Our calculations introduce “symplectic Hubbard operators”: an extension of the slave boson Hubbard operators that preserves both spin rotation and time-reversal symmetry in a large N expansion, permitti...
متن کاملNonlinear conductance for the two channel Anderson model.
Using the integral equations of the Noncrossing Approximation, the differential conductance is computed as a function of voltage for scattering from a two channel Kondo impurity in a point contact. The results compare well to experimental data on Cu point contacts by Ralph and Buhrman. They support a recently proposed scaling hypothesis, and also show finite temperature corrections to scaling i...
متن کاملConformal Field Theory Approach to the Two-Channel Anderson Model
The two-channel Anderson impurity model serves as a prototype for describing heavy-fermion materials with a possible mixed-valent regime with both quadrupolar and magnetic character. We report on the low-energy physics of the model, using a conformal field theory approach with exact Bethe Ansatz results as input.
متن کاملMagnetoresistance in the Two-Channel Anderson Lattice
The paramagnetic phase of the two-channel Anderson lattice model in the Kondo limit is investigated in infinite spatial dimensions using the noncrossing approximation. The resistivity exhibits a Kondo upturn with decreasing T , followed by a slow decrease to a finite value at T 0. The decrease reflects lattice coherence effects in concert with particle-hole symmetry breaking. The magnetoresis...
متن کاملMIXED VALENT SEMICONDUCTORS : SmB6
An overview is given of the experimental and theoretical evidence that SmB, is a homogeneously mixed valent semiconductor. It is emphasized that the experimental transport properties imply that the Fermi surface is either extremely small or non-existent, and that rather general theoretical considerations support the possibility of a gap at the Fermi level.
