Abstract
We develop further the approach to derived differential geometry introduced in Costello's work on the Witten genus (arXiv, 2011). In particular, we introduce several new examples of L spaces, discuss vector bundles and shifted symplectic structures on L spaces, and examine in some detail the example of derived loop spaces. This paper is background for a forthcoming paper in which we define a quantum field theory on a derived stack, building upon Costello's definition of an effective field theory (AMS Monographs, 2011).
