Curriculum
Vitae

Various experimental techniques have been advanced in recent years to
measure non-equilibrium energy transformations on the microscopic
scale of single molecules. In general, the systems studied in the corre¬
sponding experiments are exposed to strong thermal fluctuations and
thus the relevant energetic variables such as work and heat become sto¬
chastic.
This thesis addresses challenging theoretical problems in this active field
of current research: (i) Exact analytical solutions of work and heat distri¬
butions for isothermal non-equilibrium processes in suitable models are
obtained;
(2)
Corresponding solutions for cyclic processes involving two
different heat reservoirs are found;
(3)
Optimization of periodic driving
protocols for such cyclic processes with respect to maximal output power,
efficiency, and
minimal
power fluctuations is studied·
The exact solutions for work and heat distributions provide a reference for
theoretical investigations of more complicated models, giving insight into
the structure of the tail of work distributions and serving as valuable test
cases for simulations of the underlying stochastic processes.
