摘要：

I describe a simple class of alpha-attractors, generalizing the single-field Cl. model of inflation in supergravity. The new class of models is defined for 0 < alpha less than or similar to 1, providing a good match to the present cosmological data. I also present a generalized version of these models which can describe not only inflation but also dark energy and supersymmetry breaking.
