Effects of non-magnetic impurities on spin-fluctuations induced superconductivity
We study the effects of non-magnetic impurities on the phase diagram of a system of interacting electrons with a flat Fermi surface. The one-loop Wilsonian renormalization group flow of the angle dependent diffusion function D(θ1, θ2, θ3) and interaction U(θ1, θ2, θ3) determines the critical temperature and the nature of the low temperature state. As the imperfect nesting increases the critical...
متن کاملEffects of nonmagnetic impurities on the spin transport property of a graphene nanoribbon device.
Using a nonequilibrium density functional calculation, we investigated the electronic transport properties and fundamental mechanism of spin polarization as a function of the location of impurities from the center to an edge of a graphene nanoribbon device (GND) with zigzag edges. A center-located impurity enables both edges to be enhanced with respect to their spin transports whereas an edge-l...
متن کاملSpin-Fluctuation Mechanism of Superconductivity in Cuprates
Normal and superconducting state spectral properties of cuprates are theoretically described within the extended t-J model. The method is based on the equations of motion for projected fermionic operators and the mode-coupling approximation for the self-energy matrix. The dynamical spin susceptibility at various doping is considered as an input, extracted from experiments. The analysis shows th...
متن کاملNonmagnetic impurities in the spin-1 Õ2 kagome antiferromagnet
Motivated by recent experiments on ZnCu3 OH 6Cl2, we study the inhomogeneous Knight shifts local susceptibilities of a spin-1 /2 kagome antiferromagnet in the presence of nonmagnetic impurities. Using high temperature series expansion, we calculate the local susceptibility and its histogram down to about T=0.4J. At low temperatures, we explore a Dirac spin liquid proposal and calculate the loca...
متن کاملSpin - fluctuation superconductivity in the Hubbard model
The theory of the superconductivity mediated by kinematic and exchange interactions in t?J and two-band Hubbard models in a paramagnetic state is formulated. The Dyson equations for the matrix Green functions in terms of the Hubbard operators are obtained in the non-crossing approximation. To calculate superconducting T c a numerical solution of self-consistent Eliashberg equations is proposed.
