HOW THE KONDO EFFECT CAN EXIST IN Gd INTERMETALLIC COMPOUNDS
Based on the crystal and magnetic structural properties of some Gd intermetallic compounds, it is shown that with increasing conduction electron concentration, Gd experiences electronic and magnetic instability, and that these behaviors point to the appearance of Kondo Lattice. We suggest that the conduction electrons have gained local character. It is shown that Kondo effect should be observed...
متن کاملMultichannel Kondo approach to the cuprate and recent laser ARPES data
The existing theoretical approaches have been unable to confront the large corpus of outstanding data on the cuprate superconductor in a persuasive and unified manner. There is a general opinion now growing that these theories miss some essential points. We propose one based on multichannel Kondo effect that is physically justifiable and confronts the data adequately. In addition to earlier da...
متن کاملادغام الگوی شبکهای هولشتاین - کاندو برای توصیف نظریه ابررساناهای دمای بالا
It is a common knowledge that the formation of electron pairs is a necessary ingredient of any theoretical work describing superconductivity. Thus, finding the mechanism of the formation of the electron pairs is of utmost importance. There are some experiments on high transition temperature superconductors which support the electron-phonon (e-ph) interactions as the pairing mechanism (ARPES),...
متن کاملسیستمهای ناکام و همبسته الکترونی
Quantum phases and fluctuations in correlated electron systems with frustration and competing interactions are reviewed. In the localized moment case the S=1/2 J1 - J2 - model on a square lattice exhibits a rich phase diagram with magnetic as well as exotic hidden order phases due to the interplay of frustration and quantum fluctuations. Their signature in magnetocaloric quantities and the hig...
متن کاملSelection Rules for Two-channel Kondo Mod- Els of U Ions in Metals
Symmetry based selection rules are developed providing minimal criteria for the existence of two-channel Kondo interactions between conduction electrons and the low energy degrees of freedom on U 4+ and Ce 3+ in a metal host, assuming that the underlying microscopics are regulated by the An-derson Hamiltonian. An additional dynamic selection rule is imposed on Ce 3+ ions. The selection rules re...
