Title: Geometry of quantum response in open systems
Abstract: I shall describe a theory of adiabatic response for open systems
governed by Lindblad evolutions. The theory gives quantum response a
geometric interpretation induced from the geometry of Hilbert space. For a
two level system the metric turns out to be the Fubini-Study metric and the
symplectic form the adiabatic curvature. Nice things happen when the metric
and symplectic structures are {\em compatible}. I shall give examples of
compatible physical systems. Based on joint work with Fraas, Graf and
Kenneth (
