Classical real-time lattice simulations play an
important role in understanding non-equilibrium phenomena
in gauge theories and are used in particular to model the
prethermal evolution of heavy-ion collisions. Due to instabilities,
small quantum fluctuations on top of the classical background
may significantly affect the dynamics of the system.
In this paper we argue for the need for a numerical calculation
of a system of classical gauge fields and small linearized fluctuations
in a way that keeps the separation between the two
manifest. We derive and test an explicit algorithm to solve
these equations on the lattice, maintaining gauge invariance
and Gauss’ law.
