Scattering Theory for Delta-Potentials Supported by Locally Deformed Planes,ness of the wave operators with respect to a suitable reference dynamics. Additionally, we provide an explicit expression for the related scattering matrix and show that it converges to the identity as the deformation goes to zero (giving a quantitative estimates on the rate of convergence).

Thermodynamic Properties of Ultracold Fermi Gases Across the BCS-BEC Crossover and the Bertsch ProbIn this chapter we review the thermodynamic properties of ultracold Fermi gases in which the strength of the interaction is continuously varied. The system features a crossover between a state described by the BCS theory of superconductivity and a Bose-Einstein condensate. A discussion of the Bertsch problem is presented.
