Microcanonical Windows On Quantum Operators

Abstract

We discuss the construction of a microcanonical projection WOW of a quantum operator O induced by an energy window filter W, its spectrum, and the retrieval of canonical many-time correlations from it.

Featured image: Pictorial representation of the observable O and of the microcanonical projected WOW.
