We consider the internal structure of a d-wave heavy-fermion superconducting condensate, showing that it necessarily contains two components condensed in tandem: pairs of quasiparticles on neighboring sites and composite pairs consisting of two electrons bound to a single local moment. These two components draw upon the antiferromagnetic and Kondo interactions to cooperatively enhance the super...

This book is a collection of review papers presented at a meeting held at Squaw Valley, California in the summer of 1964. Most of them are concerned with methods of chemical physics as applied to biological problems. The exception is an excellent article on molecular genetics by F. Gros, entitled "The Cell Machinery." It does not include, however, the recent work on the genetic code by Khorana....

Using ab initio calculations, the hydrogen desorption from Magnesium hydride (MgH2) was studied. We presented the calculated nuclear quadrupole coupling constants (NQCCs) of hydrogen atom in various systems of MgH2. The effect of interactions of some metal atoms as well as Boron atom with MgH2 host matrix; (MgH2+M) nanostructures (M=Al, Ti, V, Fe, Ni ...

Silver and gold, together with copper, form the transition metal group IB elements in the periodic table and possess very different nuclear magnetic resonance (NMR) spectroscopic properties. While there is only one gold isotope ((197)Au), which has a spin of 3/2 and therefore a quadrupole moment, silver occurs in two isotopic forms ((109)Ag and (109)Au), both of which have a spin 1/2 and simila...

Novel applications of solid state nuclear magnetic resonance (NMR) to the study of small molecules, synthetic polymers, biological systems, and inorganic materials continue at an accelerated rate. Instrumental to this uninterrupted expansion has been an improved understanding of the chemical physics underlying NMR. Such deeper understanding has led to novel forms of controlling the various comp...

The nuclear quadrupole resonance of 14N was observed in KoPt(SCN)6 and K2Hg(SCN)4 at various temperatures. Both compounds yield large asymmetry parameters indicating the existence of asymmetric ^-electron distribution about a CN bond axis. The ionic character of metal-ligand bonds in the platinum and mercury complexes is estimated to be 28% and 58 %, respectively. The temperature dependence of ...
