Query: Configurational temperature in dry active-matter models   We show that the liquid-state-theory configurational temperature defines an
energy scale, which for dry active-matter models can be used to determine how
to adjust model parameters to achieve approximately invariant structure and
dynamics when density is changed. The required parameter changes are calculated
from the variation of a single configuration's configurational temperature upon
a uniform scaling of all coordinates. The formalism developed applies for
models involving a potential-energy function with hidden scale invariance. The
procedure is illustrated by computer simulations of the Kob-Andersen binary
Lennard-Jones model with active Ornstein-Uhlenbeck dynamics in three dimensions
and the two-dimensional single-component Yukawa model with active Brownian
particle dynamics. For the latter model we also show how the configurational
temperature may be applied for estimating the MIPS phase boundary, in effect
reducing by one the dimension of the parameter space. We finally propose that
the ratio between the equilibrium-system temperature corresponding to actual
potential energy and the configurational temperature provides a useful measure
of how far an active-matter system is from thermal equilibrium.
