Covariant operator bases for continuous variables

Coherent-state representations are a standard tool to deal with continuous-variable systems, as they allow Essential Oils Products one to efficiently visualize quantum states in phase space.Here, we work out an alternative basis consisting of monomials on the basic observables, with the crucial property of behaving well under symplectic transformat
