Many observables of interest in particle and nuclear physics intrisically involve the passage of time. Well-known examples include scattering amplitudes and transport properties. While lattice QCD is an ab initio tool to compute the spectrum of stable hadrons and many other quantities of interests, addressing intrisically real-time observables is a great challenge. Since lattice QCD is formulated in Euclidean time, an analytic continuation is in general necessary to recover the real-time observables. However, in some cases the real-time physics is encoded in stationary observables, making them accessible to lattice QCD calculations.
