This thesis reveals how the feedback trap technique, developed to
trap small objects for biophysical measurement, could be adapted
for the quantitative study of the thermodynamic properties of small
systems. The experiments in this thesis are related to Maxwell's
demon, a hypothetical intelligent, "neat fingered" being that uses
information to extract work from heat, apparently creating a
perpetual-motion machine. The second law of thermodynamics should
make that impossible, but how? That question has stymied physicists
and provoked debate for a century and a half. The experiments in
this thesis confirm a hypothesis proposed by Rolf Landauer over
fifty years ago: that Maxwell's demon would need to erase
information, and that erasing information-resetting the measuring
device to a standard starting state-requires dissipating as much
energy as is gained. For his thesis work, the author used a
"feedback trap" to study the motion of colloidal particles in "v
irtual potentials" that may be manipulated arbitrarily. The
feedback trap confines a freely diffusing particle in liquid by
periodically measuring its position and applying an electric field
to move it back to the origin.
