Spin-liquid behavior in electronic griffiths phases.

چکیده
We examine the interplay of the Kondo effect and the RKKY interactions in electronic Griffiths phases using extended dynamical mean-field theory methods. We find that sub-Ohmic dissipation is generated for sufficiently strong disorder, leading to the suppression of Kondo screening on a finite fraction of spins, and giving rise to universal spin-liquid behavior.

Effective model of the electronic Griffiths phase
The recent discovery of a number of heavy fermion materials with non-Fermi liquid (NFL) thermodynamic and transport properties has been followed by a significant theoretical effort to understand the origin of the NFL behavior.1 In the cleaner systems, the proximity to a quantum critical point appears to dominate many of the observed properties.2–10 In other heavy fermion systems disorder seems ...

The classical J1-J2 Heisenberg model on bipartite lattice exhibits "Neel" order. However if the AF interactions between the next nearest neighbor(nnn) are increased with respect to the nearest neighbor(nn), the frustration effect arises. In such situations, new phases such as ordered phases with coplanar or spiral ordering and disordered phases such as spin liquids can arise. In this paper we ...

Cuprate Liquid Crystal Recent experimental work has revealed exotic electronically ordered phases in correlated electron systems akin to those seen in conventional liquid crystals. These effects have manifested themselves as anisotropic transport properties, in which conductivity depends upon direction within the sample. Hinkov et al.

متن کاملAn exact spin liquid state on the kagome lattice with topological order
We find an exact spin liquid state without time reversal symmetry on the kagome lattice with odd number of electrons per unit cell and explicit wave functions for all eigenstates. We also obtain that all spin-spin correlations are zero except trivial cases. We then show that there are anyonic excitations in our model. Finally, we demonstrate the existence of ground state degeneracy and gapless ...
متن کاملM ay 1 99 7 Magnetic properties of strongly disordered electronic systems
We present a unified, global perspective on the magnetic properties of strongly disordered electronic systems, with special emphasis on the case where the ground state is metallic. We review the arguments for the instability of the disordered Fermi liquid state towards the formation of local magnetic moments, and argue that their singular low temperature thermodynamics are the “quantum Griffith...
