We address the problem posed by the inhomogeneous trapping fields when using ultracold fermions to simulate strongly correlated electrons. As a starting point, we calculate the density of states for a single atom. Using semiclassical arguments, we show that this can be made to evolve smoothly towards the desired limit by varying the curvature of the field profile. Implications for mutually inte...

Understanding multi-dimensional data and in particular multi-dimensional dependencies is hard. Information visualization can help to understand this type of data. Still, the problem of how users gain insights from such visualizations is not well understood. Both the visualizations and the users play a role in understanding the data. In a case study, using both, a scatterplot matrix and a HyperS...

We study a dynamic regulation model where firms’ actions contribute to a stock externality. The regulator and firms have asymmetric information about serially correlated abatement costs. With price-based policies such as taxes, or if firms trade quotas efficiently, the regulator learns about the evolution of both stock and costs. This ability to learn about costs is important in determining the...

This lecture gives a basic introduction into some aspects of the unconventional superconductivity. First we analyze the conditions to realize unconventional superconductivity in strongly correlated electron systems. Then an introduction of the generalized BCS theory is given and several key properties of unconventional pairing states are discussed. The phenomenological treatment based on the Gi...

We study the effect of supersymmetric contributions to the effective quark transition b → sγγ, including leading order QCD effects. We apply the discussion to the decay Bs → γγ. In all generality the amplitude for the two-photon emission is strongly correlated to the b → sγ amplitude which is sharply constrained by experiment. A quite general statement follows: as long as non standard physics a...

A social network is not only a system of connections or relationships, but pathways along which ideas from various communities may flow. Here we show that the economic development of U.S. states may be predicted by using quantitative measures of their social tie network structure derived from location-based social media. We find that long ties, defined here as ties between people in different s...

This paper studies an overlapping generations model with multiple securities and heterogeneously informed agents. There are two types of multiplicity of equilibria, one due to noisy rational expectations and the other resulting from self-fulfilling prophecies. Under general conditions, there exists an equilibrium in which stock returns are highly volatile and strongly correlated, even if all un...
