NRG calculations of the ground-state energy: application to the correlation effects in the adsorption of magnetic impurities on metal surfaces

The ground-state energy of a quantum impurity model can be calculated using the numerical renormalization group with a modified discretization scheme, with sufficient accuracy to reliably extract physical information about the system. The approach is applied to study binding of magnetic adsorbates modeled by the Anderson-Newns model for chemisorption on metal surfaces. The correlation energy is largest in the valence-fluctuation regime; in the strong-coupling (Kondo) regime the Kondo-singlet formation energy is found to be only a minor contribution. As an application of the method to more difficult surface-science problems, we study the binding energy of a magnetic atom adsorbed near a step edge on a surface with a strongly modulated surface-state electron density. The zero-temperature magnetic susceptibility is determined from the field dependence of the binding energy, thereby providing an independent result for the Kondo temperature TK, which agrees very well with the TK extracted from a thermodynamic calculation.Comment: 4 page

After 20 Years of Status Quo: The Failure of Gradualism in Slovenia’s Post-Socialist Transition

In the past 20 years, the Slovenia has been praised as the richest former socialist country, having accomplished the advancement from borrower into donor status at the World Bank and having entered the European Monetary Union as the first country from former socialist block. In the due course of transition to market, Slovenia adopted the gradualist approach to economic reform, emphasizing gradual privatization, excessive regulation of the labor market and financial sector as well as the slow stabilization of public finances. In this paper, we review macroeconomic performance of Slovenia in past two decades in a comparative perspective. The paper outlines the growth trajectory of Slovenia from the onset of Habsburg Empire to the present. We showed that until 1939, Slovenia has almost fully converged to the income per capita frontier of Austria and Italy while the income per capita diverged substantially in the period 1945-1990 from Western European frontier. We review the contours of labor market protectionism, state dominance in banking and financial sector and emergence of the corporate oligarchy as the main symptoms of stalled economic performance given a substantial differential in income per capita between Slovenia and EU15. Moreover, we demonstrate how former communist elites transformed into powerful networks of interest groups which preserved status quo from socialist period through systemic blockade of key economic reforms to stabilize public finances in the light of age-related pressures and to boost productivity growth and structural change.post-socialist transition, macroeconomic stabilization, economic growth, political economy, Slovenia
