Query: Driven Tracers in a One-Dimensional Periodic Hard-Core Lattice Gas   Totally asymmetric tracer particles in an environment of symmetric hard-core
particles on a ring are studied. Stationary state properties, including the
environment density profile and tracer velocity are derived explicitly for a
single tracer. Systems with more than one tracer are shown to factorise into
single-tracer subsystems, allowing the single tracer results to be extended to
an arbitrary number of tracers. We demonstrate the existence of a cooperative
effect, where many tracers move with a higher velocity than a single tracer in
an environment of the same size and density. Analytic calculations are verified
by simulations. Results are compared to established results in related systems.
