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 ...
متن کاملGriffiths phase, metal-insulator transition, and magnetoresistance of doped manganites
A phenomenological model is developed for systematic study of the universal features in metal-insulator transition and magnetoresistivity of mixed-phase manganites. The approach is based on utilization of some hypothesis appropriate to the Preisach picture of the magnetization process for half-metallic ferromagnets and an assumption that in doped manganites a Griffiths-type phase exists just ab...

متن کاملSpin-liquid behavior in electronic griffiths phases.
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.
متن کاملkids and teenager are sleepy at school because the electronic media they have in their bedrooms leads them to have delayed sleep phase disorder (dspd)
bserved by many teachers that most of the time, mumbling and searching for their intended words, students complain why they have forgotten the words they have learned in the previous semesters. they ask for some new ways that may help them to recall and apply the learned words more efficiently, since as they declare one of the most important skills in foreign language learning is having a g...
