The Quantum Szilard Engine: Interactions, Impurities and Dynamics
(2016) PHYM01 20161Mathematical Physics
Department of Physics
- Abstract
- In this thesis, different aspects of the quantum Szilard engine are studied using the configuration interaction method. The engine is modelled as a one-dimensional infinite well.
The effects of a contact-interaction are examined and it is found that attractive contact-interactions can improve the work output at certain temperatures of an engine that has bosons as a working medium.
The role of impurities in the engine is investigated and found to have a large impact on the low-temperature behaviour of the engine.
Dynamics of a single-particle engine are considered in order to identify finite-speed effects in the engine's cycle. - Popular Abstract
- What role does information play in physics? This is a question that physicists have been discussing for over a decade. It turns out that-by utilizing information as fuel-it is possible to create a heat engine driven with only a single heat reservoir, which originally was thought to violate the second law of thermodynamics. In this thesis, different aspects of a quantum version of such an information heat engine has been studied.
