  A ballistic atom pump is a system containing two reservoirs of neutral atoms
or molecules and a junction connecting them containing a localized time-varying
potential. Atoms move through the pump as independent particles. Under certain
conditions, these pumps can create net transport of atoms from one reservoir to
the other. While such systems are sometimes called "quantum pumps," they are
also models of classical chaotic transport, and their quantum behavior cannot
be understood without study of the corresponding classical behavior. Here we
examine classically such a pump's effect on energy and temperature in the
reservoirs, in addition to net particle transport. We show that the changes in
particle number, of energy in each reservoir, and of temperature in each
reservoir vary in unexpected ways as the incident particle energy is varied.
