    "abstract": "The Bures distance between two displaced thermal states and the corresponding\ngeometric quantities (statistical metric, volume element, scalar curvature) are\ncomputed. Under nonunitary (dissipative) dynamics, the statistical distance\nshows the same general features previously reported in the literature by\nBraunstein and Milburn for two--state systems. The scalar curvature turns out\nto have new interesting properties when compared to the curvature associated\nwith squeezed thermal states.",
