Heavy Fermion Superconductivity

Heavy-fermion compounds are ideally suited to study cooperative phenomena in highly correlated electron systems. We discuss local-moment magnetism and heavy-fermion band magnetism in the exemplary systems CeCu 2 Ge 2 and Ni-rich Ce(Cu 1− x Ni x )2 Ge 2, respectively. In addition, the coexistence of long-range antiferromagnetic order and heavy-fermion superconductivity in UM 2 Al 3 (M: Ni, Pd) will be addressed.

The Impact

Abstract. Svalbard is a remote and scarcely populated Arctic archipelago, and is considered to be mostly influenced by the long-range transported air pollution. However, there are also local emission sources such as coal and diesel power plants, snowmobiles and ships, but their influence on the background concentrations of trace gases have not been thoroughly assessed. This study is based on tropospheric ozone (O3) and nitrogen oxides (NOx) data collected in three main Svalbard settlements in spring 2017. In addition to these ground-based observations, radiosonde and O3 sondes soundings, ERA5 reanalysis and BrO satellite data have been applied in order to distinguish the impact of local and synoptic-scale conditions on the NOx and O3 chemistry. The measurement campaign was divided into several sub-periods based on the prevailing large-scale weather regimes.The local wind direction at the stations depended on the large-scale conditions, but was modified due to complex topography. The NOx concentration showed weak correlation for the different stations and depended strongly on the wind direction and atmospheric stability. On the contrary, the O3 concentration was highly correlated among the different measurement sites and was controlled by the long-range atmospheric transport to Svalbard. Lagrangian backward trajectories have been used to examine the origin and path of the air masses during the campaign.

Random Method

Predictions of wet and dry days made with an ultra-long-range weather prediction method for the Los Angeles, St. Louis, and Boston regions for November 1977–April 1978 are compared with the actual weather. The method predicted, on average, 61% of the wet and dry days correctly. A climatologically based random prediction method is developed and is shown to predict for the same data set, on average, 57% of the wet and dry days correctly. The monthly averages of the daily predictions in each category are highly correlated for the two methods. The ultra-long-range method is shown to predict with about the same skill as the random method for the period investigated.

The bandgap of solid C 60 is found to be 2.3±0.1 eV . The on-site molecular C 60 Coulomb interaction (U) as determined from the KVV C 60 Auger spectrum is found to be 1.6 ±.2 eV . This value of U is shown to be consistent with Frenkel type molecular excitons in the 1.5–2 eV range. These results lead us to suggest that doped C 60 should be considered as a highly correlated system with U/W comparable to that in high T c cuprates. The Auger spectroscpoy results are consistent with a rather long range Coulomb interaction on a single bucky ball indicating that a Hubbard model is not suitable to describe the electronic structure of a C 60 molecule.

Potential Curves

For the model organosilicon cation H3N···SiH3+, potential curves have been calculated by density functional theory at the B3LYP level, by both MP2 and MP4 perturbation procedures and by a Coupled Cluster approach. Relative to the analogous potential curve for the uncharged adduct, H3N···SiH4, a considerable increase of the long-range Si···N interaction accompanied by bond shortening is predicted. For chemical comparison, the structure of the "double R2N-twister" dication salt, [C6H4(CH2NR2)2-Si-(R2NCH2)2C6H4]++Cl2-, reported in the literature as a non-crystalline solid, was optimized by DFT calculations and a minimum for the hexacoordinated organosilicon center with each two Si···N bonds of different lengths was located. To test the reliability of the quantum chemical procedure, in addition the analogous and structurally characterized dication salt, [(3-picoline)4SiH2]++[Cl-···(HCCl3)2]2, which contains a hexacoordinated Si center with 4 equivalent Si···N interactions, has been selected to reproduce its structure by DFT optimization. Both hexacoordinated, tetra-N-surrounded Si dications, substantiate the increase of long-range Si···N interactions as predicted by the potential curves for the model adduct H3N···SiH3+ based on highly correlated calculations.
