Abstract
The emergence of time reversible phenomena from a sequence of time-reversible steps has been a long standing question in microscopic thermodynamics and non-linear dynamics. A promising physical system to study this sort of time-irreversibility involves a microparticle exploring a physical landscape via thermal agitation. If the imaging frequency can be sufficiently increased, such a system can provide access to the time-reversible ballistic regime of brownian motion, allowing for studies of the consumption and production of entropy on the microscale. Using an ultra-fast imaging system developed by previous IWU physics students, our studies may be able to access this regime, allowing us to test fluctuation theorems.
